I don't draw that much anymore, even though I would very much like to. I used to attribute this to a lack of time -- I'd hate to start on a drawing, if I suspect I will not get to finish it -- but now I believe there's another reason behind it: it's difficult for me to start if other people are around me. Especially other people who are much better at it than myself.
It's a stupid reason, I know, but I can't shake it. I hope I someday will, because right now I'm getting nowhere.
