I've mentioned this before, but I used to take for-ev-or to complete a drawing. Part of that is because it was so detailed, but I believe another large part of it is that I wanted to keep working until it felt just right -- something I could be super proud of. I put a lot of pressure on each artwork.
Challenging myself to draw quickly, like in the 100 Day Project, has really helped me shake free of that. Now, since I know that I don't have to take months to complete a drawing, each project feels like less pressure. Every work of art isn't a masterpiece that I'm going to sell countless prints of. That's ok. It's ok to just be ok sometimes. What's important is to keep moving.
I've found creating some sort of structure for myself frees me up. I'm not so overwhelmed by all the possibilities. It's also fun because then it becomes something of a challenge -- to create a design that's interesting with limited elements. Constraints that enable (that was the title of an article that I read in grad school).
(You'd think I'd also obsess over having straight lines and perfect symmetry, but nope. I actually perfect the wobbly and human-ness of impercision)
There are lots of ways to be an artist.
