Along a similar vein, there was a scene in some documentary about artists that really inspired my wife. In it, some illustrator said that he went to his studio every day at the same time, no matter if he had an idea or not. He said that if he got there and didn’t have an idea, he’d just sharpen his pencils. To paraphrase him, he said, “Stand there sharpening pencils long enough, and eventually you’ll find you have something you want to draw.”
