I feel pretty bad about it, I want to draw but I just: don't. Days pass and I don't do a single doodle but I've read some artists going through the same and that's somewhat of a relief at least, knowing we are not alone and so many of us are going through the same struggle, so if you also feel terrible because you feel you're wasting your time just know that It's not just you, you are not alone in this.

Maybe just me, but when I get that way, it helps to do something to remember the fun of drawing. Like Gartic.io or something. Dopamine boost!
