It's hard to escape the rat race without working for yourself.
The catch-22 is, when you start working for yourself, you will be working longer hours for the first 5 years than you worked for your boss. But once you succeed, you'll have the possibility to truly be free. Of course the next catch-22 is that by that point, you will have become so addicted to success that you will likely never go minimalist. At least not until after another 5 or 10 or 20 years of really feeling the pain of it.
This issue is veritable Sarlacc pit. Freedom ain't free.
All that said, deciding to work for myself was one of the best decisions I've made in my life.

MY PROJECT BINDER IS RIVALING MY DAILY ROUTINE/ SCHEDULE AS A KEEPER FOR MY LIFE PURPOSE WORK -- LEMME TRY TO BREAK THIS NEW TECHNIQUE DOWN SO YOU CAN APPLY IT TO YOUR LIFE
Here's some tips for your Project Binder: 
You need a 3-ring binder; One table of contents page that has all the projects listed numbered 1 through X (whatever number the last project is); Print out a separate page for each project with the number in the upper-right hand corner and the name of the project in rather large font on the front of the page; Insert all your projects into the projects binder; Flip through your project binder a few times a day, and when you flip through if you have an idea write on the page the date and the idea.  Anytime you mention a task that can be done -- highlight just that task with a highlighter.  E.g., 12/03/18 Today I decided it might be a nice strategy to design attorney's websites after they give me the photos they want to use.  Research if this is how web developers typically operate.  I would highlight the last sentence in that entry because it's an action (I bolded it instead of highlighting, but you use a pink highlighter).  Highlight all discernible actions in your entries.  Use a pink highlighter because yellow highlighters don't jump out as much.  You want the actions to jump out. Nothing ever comes out of your projects binder.  So, don't put anything in there that you're not gonna leave in there.  If you need more space for notes, add a new page and use the same number in the upper-right hand corner of that page as the project that that page corresponds to.  E.g., if you have 3 pages for project 39 in your journal, all three pages will have 39 in the upper-right hand corner; On your table of contents page highlight your 3 most urgent projects; Start to become a doer.  Start to think ahead in terms of strategy.  Identify actions you can take.  Start to identify actions you can take now to avoid foreseeable obstacles; Print the table of contents out and add as first page of your Project Binder.  No other shit goes in your project binder.  Just the table of contents page and a numbered page for each project with the name of the project written on each project page.  Don't put any theory in this binder.  Don't put your one-sheet in this binder.  None of that shit.  This Project Binder is just for projects; Print a second copy of the table of contents page and keep it with you.  Read it before you go to bed.  Read it while you're taking a shit.  This is your new reading material.  There's no better reading material than your table of contents, your list of pending projects;  PM me if you have any questions about this because this is a really powerful technique I've developed here.  This will help give you a reason to make the paradigm shift from thinker to doer. Here's my Project Binder.  Notice that the binder is on the thinner side.  If your binder is too big, you're gonna be less likely to carry it around with you, see.  Don't get too big of a binder.  You want this to be like your new bible, something that you have in your hand and within arm's reach at all times.

This is an excerpt of my Table of Contents page: (I had to redact some personal stuff out of this, so this is just a sample.)
REMINDER: These are all projects.  If it’s not a project it doesn’t go in the Project Binder.  Keep your petty school and work stuff out of this Project Binder as well as your one-off to-do’s.  You need to develop a sense of what belongs and what doesn’t belong in the Project Binder for this technique to work for you.  A couple of themes of the projects in the Projects Binder is a certain level of complexity and a certain level of ongoingness.  But don’t let those concept limit what goes in here either.  You experiment.
