I just shared this quote with a friend, and thought it might be worth repeating here. "Inspiration is for amateurs; the rest of us just show up and get to work. If you wait around for the clouds to part and a bolt of lightning to strike you in the brain, you are not going to make an awful lot of work. All the best ideas come out of the process; they come out of the work itself. Things occur to you. If you're sitting around trying to dream up a great art idea, you can sit there a long time before anything happens. But if you just get to work, something will occur to you and something else will occur to you and something else that you reject will push you in another direction. Inspiration is absolutely unnecessary and somehow deceptive. You feel like you need this great idea before you can get down to work, and I find that's almost never the case.”
As far as art goes, these are some of the best words of advice. I have this printed out and posted in my studio space and in my bedroom so I see it daily. It's easy to over think an idea, to kill it before it's born and sit around and think of all sorts of reason to not make art. Ultimately, you just have to do it, if you want to or not. Do it. Don't stop. Do. Not. Stop.
