I once saw a video of an autistic man who was able to recreate skylines of cities perfectly, with no reference or perspective lines, and all he needed to do was look at it once, and he could draw that shit in a room later with no reference. Quit doubting your abilities and working within an others framework.
Everything is a fucking outline, or a fucking gradient. You don't need a giant scaffold to build a fucking outline, and people have turned that scaffolding into an artform itself, stop it, just fucking draw, a lot, a lot a lot, your rules and guides won't save you from being a shitty artist, just work at it, it's very hard and boring studying outlines, using magic lines that don't exist in reality to help guide you is just a waste of time, there is nothing wrong with doing art your way, stop feeling like a failure because you don't understand fake concepts explained by some jackass who's only trying to confuse you with words and explanations instead of just drawing.
In art, perspective is a convoluted concept. Oh? You need me to draw lines? A grid? Ohhh I see, because rules, well fuck you, fuck your rules, just draw, if you suck draw better, end of, maybe instead of confusing people with your silly artist words, just SHOW them how to draw, because none of your words make sense.
Look, symmetry of life

*after eating your 1,000th human meat burger*
"Ahhhh, finally, all my feelings of insecurity are gone! On account of I just ate 1,000 human meat burgers! When human meat burgers were legalized I knew it was a good day for me, and I immediately went out and bought my first human meat burger. After tasting the first bite of that delicious human meat burger I knew I had finally found a way to feel truly triumphant in life; By consuming human flesh! You see, by consuming human flesh I am proving I have what it takes to compete in this competitive world, and now that I've eaten 1,000 human meat burgers I'm more than ready to tackle whatever life has to throw at me!"
I'm SO horny for VAGINA right now that I'm going to go WORK OUT in the hopes that it will make my body sexy enough for me to GET SOME (it won't, because I need money to get some, like a lot of it, and I've had the means of production denied to me so I have no way to make money, thus gatekeeping pussy from me)
