I have answered something similar yesterday so i'll put them here as well :
- art is a personal process, do not compare yourself with other artists and be patient and nice to yourself. Even if you see 12 yo mastering color theory and anatomy, we all learn at a different speed !
- DO NOT BURN OR THROW AWAY YOUR UGLY SKETCHBOOKS/DRAWINGS they are an anchor to see how much you've progressed !!! very important !!
- don't be anxious about trying out new stuff. Get dirty with paint/charcoals, learn that it's ok to make ugly drawings, and put those ideas on paper/canvas !! Do not overthink the process and just throw stuff in there :) if you're not satisfied about it, it's gonna be a good occasion to do a redraw ! :D
- also... don't burn yourself out !!!!! Take a break, play your favorite video game, watch your favorite movie, but if art is not your job, never force yourself to draw if art tires you in any way !!!

However I will add :
- don't draw to please an audience, draw what you genuinely like and the audience will come for how passionate you are about it !
- doing studies is good, but don't let it get to your head and make you overthink the process. Never forget what makes you thrive about drawing !

i hope this helped ♥
