basically you need to learn lighting framing timing cuts editing camera and lenses  aspect ratios colors, you can take it as far as you want if you wanna learn full film making
but deepening on what is your end goal you might add a bit of writing too

you dont need too much of that if you only wanna make simple youtube videos and you can start by  focus maybe only on editing

you are literally tabbing into art and there is no end to how much you can learn and improve with it so be wise with it
 
 
 
 
 

I've been doing it every day. It is so fun to just socialize and you can just do it while you go about your day. There really is no downside to just doing it when you get the chance and building a daily habit. 
I just started a few weeks ago and after like 30 approaches I went from having extremely horrible anxiety to just having fun and not being worried. Interactions already going way better. It's like an ice bath, you just can't think about it b. You meditate and stay present and when the opportunity arises you just do it instead of making it be this whole stressful thing.
