'I think it's good to have a lot of projects going at once so you can bounce between them. When you get sick of one project, move over to another, and when you're sick of that one, move back to the project you left. Practice productive procrastination.
Take time to be bored. One time I heard a coworker say, 'When I get busy, I get stupid'. Ain't that the truth. Creative people need time to just sit around and do nothing. I get some of my best ideas when I'm bored, which is why I never take my shirts to the cleaners. I love ironing my shirts - it's so boring, I almost always get good ideas. If you're out of ideas, wash dishes. Take a really long walk. Stare at a spot on the wall for as long as you can. As the artist Maira Kalman says, 'Avoiding work is the way I focus my mind'.
Take time to mess around. Get lost. Wander. You never know where it's going to lead you.'
