Do you ever suffer from creative block? And if so, what do you do to overcome it?

I embrace it. When you are blocked, you know you have something to do. And also it is not a permanent condition. A block basically leads you elsewhere and very frequently that is precisely what is needed. A block comes from doing the same thing too many times and running out of gas. As I frequently quote Picasso, “Once you’ve mastered something, you can abandon it.”
