The biggest turning point in you life as an artist is when you shift gears from thinking “I can draw these things but not those things” to thinking “I can draw anything! Quality not guaranteed, but I can draw it”
That applies to a lot of things. I remember tackling the teaching of courses I was not really well versed in, but I took them on and learned as I went. Sure, my first attempts were probably just a hair above mediocre, but I would say, "I can do this" and I did. I wound up being fairly good.
I'm a big fan of the "Souls-like" method of art.
"I will draw this over and over and over again until ot doesn't suck. I don't care how much material I waste on stuff that sucks, the one that comes out decent will be worth it all the more."
Also part of this revelation is the moment when you realize you can use reference
“Oh no, I can’t draw that, I don’t know what it looks like… wait… what if I just… LOOK IT UP??”
The moment I stopped giving a shit about my drawings being good I was up for drawing practically anything. As long as you're enjoying it, and you're improving (if you want to improve, that is.), that's all that matters.
