It is important to know when you need to stand your ground on an ethical or safety concern.  Though, it is important to be able to work as a contributing part of a team.  An employer (and for that matter clients in a self-employed capacity) are not looking for people to make their lives more difficult, they are looking for people to make their lives easier.  Sometimes, even if you are right, there is value in humility and being easy to work with. Sometimes, even when you think you are right, you might learn something from someone else.    
Based on your self-description, I wouldn't be surprised if your peers characterize you as hypercritical, condescending, blunt, rude, and insubordinate.  
What is amazing is that you have (are developing) the self-awareness of your attitude, actions and potential consequences.  Most people do not have this awareness.  You can be whomever you want--you can continue on this path, or you have the opportunity to change/evolve/grow.  
The most appropriate question is: who do you want to be?
Even in a self-employed capacity, most opportunities are going to involve interpersonal relationships and interactions.  Of which, being a team player will get you a lot further in life, business and relationships.  

I realize now that the less you do during the day, the more you let yourself relax, the harder it is to get shit done later. 
Yesterday I managed to get tons of stuff done, which definitely wasn't easy, but felt so awesome afterwards. And I slept like dead without waking up! Which is an accomplishment.
Moral of the story: do the hard things and you'll get your reward. Don't do it and suffer. Pick your poison. 
 

As I have been applying the letting go technique, I’ve encountered the following problem : I would frequently misuse it as a way to repress whatever negative emotion that may arise.
Instead of actually feeling the emotion as it comes up in my awareness, I would make the mistake of trying to « let it go » as a way to make the emotion disappear. And so, I would be in this mindset of trying to control my emotions.
 
So to counteract my tendency of using the technique to repress and control my emotions, I’ve found a new wording : whatever arises, I let it be.
 
When applying this, what I’ve noticed is that it trains me to accept the entirety of the present moment as it is, and prevents me from controlling anything. If anxiety comes up, I just let it be : I don’t try to react to it, I don’t try to control it in any way, or try to make it disappear. I just relax and let it be as it is, and I’m allowed to feel that anxiety as it is ; I don’t have to change it in any way. Actually, it’s all ok, it’s all good.
 
One thing that I’ve noticed also is that things around me start to become less and less of a problem. Precisely because I would just let everything be, they would all gradually cease being a problem by definition.
For example, if stress arises, it wouldn’t be a problem at all because I would just let it be and accept it. I would just go out and do whatever activity I need to do, while feeling that stress in my body ; I wouldn’t be as affected by it precisely because I have stopped seeing it as a problem in the first place through letting it be as it is. In other words, I would let it be part of the present moment, and so I wouldn’t be affected as much.
I would reach deeper and deeper levels of acceptance : if I am in an uncomfortable situation, I would accept the situation as it is ; if somehow I can’t accept it, I would just accept all my resistance to that situation. Again, whatever arises, I let it be.
 
Since I’m becoming more open to feeling everything, I’m having a deeper connection to all my emotions. There is less resistance to feeling more and more of my deeper emotions. It actually can become quite enjoyable at times, to be connected to yourself and to be experiencing all these cathartic moments.
 
I can start to see how « Whatever arises, I let it be » eventually leads to radical acceptance and absolute freedom, which are quite terrifying. It leads you to accepting thoughts, choices, situations and experiences that are horrifying for you. It’s all inspiring when it’s about learning how to accept failure for example ; but it becomes totally unacceptable and almost criminal when it comes to accepting the murder of a loved one. 
But then, if you truly want total emotional mastery, this is where it’s leading you towards ; you’ll have to let go of your dualities and categories of what’s ok and what’s not ok.
 
Other variations :
Whatever arises, it’s ok. Whatever arises, it’s fine. Whatever arises, let it be part of the present moment. Whatever emotion arises, let it express itself. Basically, you can get creative and come up with other ones. Keep what works and resonates with you, and ditch whatever doesn’t.
 
Potential traps (no concept or technique is completely foolproof) :
Using this technique to ignore your emotions, to avoid dealing with them, and to push them aside. You’re actually supposed to feel them. Holding onto certain emotions ; that would still be you trying to control your emotions. You’re supposed to let them be : so, if they come to pass, then you let them subside.  
Disclaimer : This is not to say that the letting go technique doesn’t work. This post is useful for people who, like me, has this weird tendency of misusing the technique to repress instead of feeling. Again, always do whatever works for you ; get creative when needed.
 
Hopefully this helps for you, as it has done for me.
 
And finally, one song to tie it all together :

@Tiny Nietzsche If your soul loves music, decouple that from piano itself.
Create a LP around your love for musi, not piano. This is a much broader notion than mastering piano. Love of music might not require you to play the piano at all.
Think more outside the box. What are new ways you could sharing your love of music.
Like maybe you could invent a new musical instrument, or whatever. Get creative here.

Sure, it's definitely doable.
You're already on the path. Just keep doing more of the same and eventually your addictions will become more and more positive. It can sometimes take months and years though, so be patient.
If you really want to drop habits for good, the secret is not to try to forcefully change them, but to mindfully observe yourself acting like a mindless chimp while engaging in the habit. Try smoking an pack of cigarettes while being constantly focused on how they are making you feel and how they are damaging your body and making you feel addicted. Don't go unconscious. As soon as you go unconscious the process stops working.
Start to apply LOTS more consciousness to your bad habits as you do them. Pay much more attention to how these habits are robbing you of a great life. At some point, the mind will just drop the habit cold, without you having to force yourself to resist.

Of course not.
Male and female attraction is asymmetrical.
They fantasize about some knight in shining armor whisking them away. Read some cheap romance novels from Walmart to understand how women think about sex/relationships. That cheap romance novel from Walmart is a woman's version of porn.
Much less important. A woman is looking for strength and leadership qualities, not looks.
Of course if all else is equal, she will pick the guy with better looks. But in practice all else is never equal. This is why a guy with below average looks can attract girls with above average looks. He compensates for it with strong inner qualities. The nice thing about this is that it's possible to cultivate these strong inner qualities. The bad thing is, this involves serious emotional labor.
In a sense being a hot girl is easy because you don't have do anything. You wear your value on your sleeve. The downside of this is that if you're not a hot girl (and definition most girls aren't), it's almost impossible to change that. So men have more flexibility in this department. But in practice very few men actualize this possibility.
Most people end up settling for someone at roughly their level of reproductive value.

@orpheos Take ownership of the problem and start acting with more passion. Fake it a bit till you make it.
Be more playful, more flirty, more proactive. Rub up on him, tease him, put your hands on him, etc.
This isn't rocket science. Don't ask how. Just do it. Learn to turn yourself on with your mind, and learn to turn him on.
If you need to watch porn, watch porn and take notes. Although really this stuff is pretty obvious.
A deeper issue you might have is shyness or fear of intimacy. Or perhaps you were raise in a family/culture which taught you to be ashamed of sex. In which case you're sexually repressed.
How do you fix that? By questioning those old beliefs to death and pushing your comfort zone and exploring sexuality. Many books have been written about sex.
Being good at sex isn't natural. It requires practice and training. Don't be afraid to practice and train. Go suck on a cucumber until you figure out a good way to do it. This kind of basic stuff is what women avoid, but it necessary if you want to get good. Don't expect good sex to happen automatically. You have to put energy and intention into it. You have to be interested in doing whatever it takes to make it good. This might mean buying books, videos, toys, courses, attending classes, watching porn, practicing, visualizing, talking with your partner, training with your partner, etc.

It's both

In practice you're gonna have to settle for some compromise. You're never going to find the perfect package. Try to make a list of everything you want in a girl, then rank it from most to least important, and then be prepared to only get 60-80% of that list (if you're lucky).
There will always be hotter girls. Attracting and maintaining 9s and 10s is very difficult in practice. The chances of attracting a 9 with a great and suitable personality is very low. And of course looks will fade too.
Perfectionism here will be disastrous.
But also, you gonna determine if she meets your basic quality standards. Otherwise you will never be satisfied with her and she will sense that off you, and it's not fair to her.
So ask yourself this question very honestly: "Is she good enough for me to settle down with? Or would I regret it in the back of my mind?"
In general you need to get very clear with yourself about what is and isn't good enough for you. You need to be clear so that you can better screen girls in the future. So you don't end up settling for something that isn't right for you. This problem is not with her, but with your lack of knowing what you want. So get more clear about that. What are the things with a girl that you're not willing to negotiate on? Make a list.
For example, I have a few basic rules that are deal-breakers: like if she smokes, drinks, likes to get tattoos, or is overweight. I just know that I will never be satisfied with that. So it's best to not even continue down that road. Physical attractiveness is more tricky because there are so many degrees of it. Sometimes a girl is right on the edge where it's not clear. Ideally you want her to be at least 30% over the edge. Any lower and you'll probably be too luke-warm about her.
I've actually invested quite a bit of time simply training my eye for physical attractiveness. You can go to the local mall and just walk around looking at random girls and asking yourself, "Would I fuck her? Yes or no?" And force yourself to quickly make that determination within a few seconds. Do this a thousand times. As you practice this more you'll get better and better at quickly determining if a girl is right for you on the level of physical attractiveness. Obviously there are many other factors beyond that. But since looks is the first screen, it's important to get clear about that screen. Self-clarity is the key.
As you become more conscious, looks will matter to you less and less and your ability to love will increase exponentially.
Determine which features of physical attractiveness matter to you and which ones don't: tits, face, ass, height, hair, legs, weight, skin color, teeth, eyes, nose, race, etc. Get clear about what your deal-breakers are. It's a lot easier when you can screen for this stuff up front. It's very painful to do it once you know her. This screening needs to be done as early as possible.

English is not my native language, so I think I will fail to explain.

But I will try. I had troubles in relationship. I tried to fix it by fixing everything outside. Nothing good happened. Then, I took responsibility for myself and started to meditate, went to Vipassana retreat, tried psychedelics and everything started to go in a positive direction in all areas of my life.

Well, I have a long way to grow to the state when I am able to surrender to the Flow and realize that everything is God. So, there are no problems whatsoever. There is no one to fix.

But from my direct experience, when you change yourself (shrink your ego) everything around changes in a positive way. That's what I suggested to OP.

Of course I don't know the situation precisely and of course this is a good thing to help people (if they ask for the help or you *must* help otherwise a person dies for example).  In general I would suggest to not try to be a smart ass  and start from yourself.

Yes, definitely.
There are phases in this work when you're doing lots of general research but not getting much tangible results. And there are phases where you're practicing a narrow set of techniques and seeing tangible results but not doing much research.
You can naturally cycle between these phases depending on what your life requires.
You'll need to dynamically balance between the two extremes.
Watching a bunch of my videos will fill your head will too much theory and not enough tangible results. And yet, that theory will serve you well in the future when you get stuck or lost.
Things tend to auto-correct themselves in the long-run. Too much theory should naturally drive you to crave results. And vice versa.

This problem should largely auto-correct itself once you have a strong sense of life purpose. A man grounded in his life purpose is to busy actualizing his bold vision for the world to have time for such nonsense. Most of your time, skills, and money should be going into your LP, so that little is left over for others to leech. Of course occasionally you can generous, but overall you're not working to help random people, you're working to actualize your vision for the world (which is a more coherent, deliberate, and powerful way to help others). Think of your life purpose as simply an organized and very strategic way of helping elevate the most people in the world according to your unique skill set. Which means that if you're not doing that, if you helping people randomly on their terms, you're actually hurting the world overall.
For example, I don't need to worry about helping every random homeless person I see on the streets because my time is better invested in shooting videos and helping people via my business. My business was designed in such a way that it already incorporates that desire to help others.
In other words, help others, but on your terms, not on their terms. Then you don't get used by vampires. Be deliberate about how you want to help people. Don't leave it up to chance. Don't wait for a homeless person to approach you.

I was in a similar situation a little while back. I played the honesty card and it went well. I explained to them why I did that and stood my ground even though they were totally against it(even weed).
First reaction was utter shock and panic but I kept calm and tried my best not to get caught in the useless debate. I just told them that no matter what they thought I was going to follow on what I believed was the right thing for me to do.
Their main fear was that I was going to become addicted, screw up my life or do an overdose and die right there. I tried to explained to them that it was all ungrounded and unjustified fears but of course they were not interested in my reasoning or my logic so I just went on to respect their "It's my home and there's no drugs in my home nonsense" because I didn't want to create unnecessary turmoil (funny enough my father had a beer in his hand while moralizing to me) . However I did told them that I planned on doing them again, just not in their home. They didn't like that but it stayed that way.
Couple weeks went by and I was just integrating and embodying more and more those insights. Also just the fact that I was finally being honest with them about what I truly felt removed a huge weight from my shoulders(I had been using psychedelics for about a year when I told them). They never talk to me about this subject anymore but I have a better relationship with them then ever. I mean they can deny it all they want but at some point I guess they just saw how my behaviour changed, how much more loving I became, how much more healthy I became. They probably don't attribute it to the psychedelics but they see me meditating every day, they see me practicing my instrument for hours and hours every day, they see me eating healthy and exercise and it shows on my body and in my mood. I am pouring passion for life onto them. I guess my behaviour got the fear of me turning into some kind of junkie out of their mind.
What I am trying to say is that sometimes you just got to speak the truth.(Depends which environnement you are in but if your parents are not against weed I assume your in a safe position as my parents were totally against it) Just make sure that you are respecting them and not going overboard with it. If they don't want that in their house respect that and do it only when they are away or in another location. Be true, be yourself and be honest that's all. If you can let life blossom in you they will see that.
I hope this is going to help you in some way?

Yes, such a period in one's life can be stressful and exhausting.
Starting a biz is not easy and eats up a lot of time and energy. But if you do it right, it will pay dividends for the rest of your life.
Starting my own biz was one of the best decisions I ever made, enough though it was challenging and stressful at times.
Just make sure you don't burn yourself out.

After watching Leo's last video about Fear i got extremely confused.
First of all it seems that Leo implies that visualization of fear is not enough to overcome fear & you need to create some identity level change alongside.
But from my personal experience Behavior Change Alone Creates Identity Level Change. For example as someone who suffers from OCD , after few months of cutting compulsions my Anxiety greatly diminished & i believe my identity changed as well in the process. I no longer react to anxiety with compulsions & have learned to accept uncertainty. (Still though i have tons of work to do). 
Just after couple of days of practicing fear visualization (i imagine and live through the worst case scenario) i noticed some changes & i am mind-blown by this information. It is what i needed my entire life.
How to create identity level change? What is the process? 
- Thank you.

So let me give you some backstory.
This summer my parents left abroad for work.(Coming back in about 2 weeks.). I experimented with some LSD while they were gone.I did 5 trips which really helped me uncover my deepest fears and demons and slowly work through them. On top of that it really helped me get in touch with my top values, as well as helping me quit smoking and go in to a plant based diet which healed my chronic gastritis.
And I want to keep going and discover the more spiritual aspects of tripping.
But since I live with my parents (I'm 19 working a part time job and trying to find my life purpose right now in case you were wondering why I still live with them. Our financial situation is kinda tough. That's Greece for ya). Anyway, If I were to trip in my room my parents would obviously know I am on something, especially since my dad has taken some LSD in his youth too. So I've realized that I have to tell them about it. They are both kind of conservative about the topic of psychedelics, even though they are ok with weed. Especially my mom.
I want to have a calm and civil discussion on the topic, but I know my mom will react quite badly because I have briefly mentioned some "research" I found about psychedelics, and my mom immediately dismissed it because "they are not legal". And it's really hypocritical because weed is illegal too. Now, I don't have anything against her obviously, I love her, she has always been there for me and I understand why she has these beliefs. ( The way she grew up, the drug culture of the 70s and 80s etc. ). She basically has psychedelics in the same bucket as cocaine, heroine etc.
Anyway, I would like to know if there are any ways to open her mind on the topic without alienating her or fighting with her.
Any advice would be greatly appreciated, thanks in advance :).

In practice you probably shouldn't because they will not understand.
It's hard to reverse an irrational paranoia. Parents tend to be closedminded about such things, like naive children pretending to be good parents. It's ironic.

I think it's more complicated than that.
Be careful taking spiritually advanced people for fools.
Channeling is a well documented phenomenon throughout history. She ain't the first one to do it.

I'm really struggling with this as well. And I'm 11 months totally clean from alcohol and drugs. I'm an addict in recovery with 12 step fellowship. But I just can't shift the binge eating and sugar cravings.
However, take a look at a thread of mine I did the other day about addiction to chaos as she said a few things that make sense to me in terms of cravings and she gave some nice responses and strategies I'm going to try with regards my food problems. 
It's not about food at all her clip but it really got me thinking about other hidden benefits that I might receive from binging and general sugar consumption. 

No, but it is a rather shallow strategy for happiness.
Is shooting up heroin bad? Nope. But don't be surprised if you end up unsatisfied with that lifestyle.
On a practical level sleeping with lots of women is just unsustainable for many reasons. In the end you'll find it takes up way too much time and energy which could be put to better use.
Consider, if you were truly happy, you'd have little need to sleep around with many women. Or really, any women at all.
You'd be a fool not to build a quality relationship with the 8.
Indeed. If you were wise you'd see that happiness is all that matters and therefore fucking as many hot women as possible would cease to interest you. But as of now you're still to unconscious, immature, and needy to realize this.
Your attachment is to your dick. So you're very much attached here.
If you really wanted to be detached you'd give up sex altogether and never think of it again. This would be the wise move. But of course you're too unconscious to pull it off.
It's not a matter of morality. It's just foolish, immature, and self-defeating.
You are thinking with your dick. Which is not way of the sage.
By all means, think with your dick as much as you want. But don't expect that to go well.
The less you think with your dick, the better your life will go, the happier you'll be.
It's counter-intuitive not to think with your dick.

- Reactive energy can get a really powerful momentum so there's a part of just being really careful on the begining of the day to not fall into reactive energy, and then if you start proactivly it's gonna build up proactiv momentum as well, so really plan and make a routine of proactive activities starting the morning
- Get your WHYs on point, Why do you want to get that exam ? what do you want from it, why is it important for you ? why is it good for you ?
And also check some inner contradictions, what could be bad about getting that exam ? what would you lose ? put some light on awareness on that and then you'll be able to eventually make some change or something to solve/get at peace with those inner contadictions, also just puting some light on it and realising that it's not that important (the Why nots) might solve them on its own without changing anything

@Aakash Well, "hot" is a relative and subjective distinction. It basically is whatever we say it is.
If you feel courageous you can post your pic on:
https://hotornot.com
And they will rate you from 0-10.
But it would really be better for your self-esteem not to submit yourself to such mob evaluation of your self-worth. In the end you gotta love your genetics however they happen to be. Can't change that (yet).
You must play with the hand life has dealt you.
If it's of any consolation, all the "hot" people will eventually become not. So this is a bullet you'll have to bite at one point or another in life. You can't really avoid it. It's just a matter of time. It's a good idea not to base your self-esteem or happiness on your physical appearance. Or else you'll be in for a world of hurt.
The great news is, you are not a physical being at all.

I didn't start any large corporation, nor did I ever use investors to start my businesses.
You just gotta be creative. You can run a small biz and do well.
Of course you'll be working long hours to make your small biz thrive. Then you'll understand why long hours are common.
There exist many opportunities for small businesses. There are many market niches which are too small to sustain large corporations so they can't compete with you.
Business is just like the animal kingdom. The biggest animals are not the only game in town. In fact, most animals are small ones. You can be a highly successful small animal. But you gotta be more creative, clever, and strategic than the big guys.
