Someone recently asked me why I only draw with a pen (a Sharpie usually). I'd never answered that before and no reason has ever formed into anything concrete. I just do. Do you ever hear your words coming from somewhere in your heart before you can answer with your brain? That happened to me. I learned why I do it and it's a durn tootin' good reason!
If I draw with a pencil it gives me the chance to erase what I don't like and I'll wear that eraser down to nothing before I ever draw anything. It will never be "good enough." When I draw with a Sharpie I have to work with my mistakes. It seems like backwards reasoning, but I feel less tentative about drawing with a pen. I know there will be something I don't like, or a stray line, but I don't have the pressure of needing to fix it or make it JUST RIGHT. It was nice to realize that.
Sometimes what ends up on the paper is nothing like what I thought I was going to draw. Going with it changes my creative thinking into a way I wasn't expecting. I think it helps my mind be less rigid and sometimes I like what comes out! I'll see something on the paper I would not have otherwise.
This is where I get all philosophical and roll my eyes at myself, but I have to point out this comparison. I think it helps me deal with life. I have to take what I have and turn it into something that works for me and make the best of it. There have been plenty of times I've been upset about the way something turns out only to realize later that something even better came out of it. That ALWAYS seems to happen. (Recently I was upset about not getting a job I was SURE I'd get. Because that didn't happen, I now have the opportunity to go to school and get BETTER jobs. Suckers!)
Drawing with a Sharpie is my reminder to myself that there is no such thing as perfect. And really, there's no need to be upset when something doesn't go my way.
