I'm getting stuck at drawing whenever I'm 20% done, I just wanna quit and start over with another drawing, drawing full bodies, scenes or even basic details wear me out, I feel pointlessly tired and since I'm drawing mostly for myself I wonder what's the point. I get stuck at practice because I feel I'm doing the same over and over and I feel like I never apply what I "learn" there and whenever I'm drawing casually I don't know how to start and when I start I don't know how to continue and if I do know I just don't feel the energy or the reason to do so, even when my drawings look pretty in comparison to my older works I start to look more at their flaws and quit them and start over from scratch or fall again into a longer hiatus. What should I do?
