I'm always interested in what very successful creative people have to say about their work lives. I was reminded today about Twyla Tharp's book called The Creative Habit. I haven't read it yet, it's one of those that I want to but haven't but I've liked all the things written about it in the Times, and here on Head Butler. (Jesse Kornbluth, the Head Butler, has a 4x a week email notice about interesting and under the radar things. I read him regularly!)
Twyla Tharpe maintains that ideas follow discipline and hard work -- after them, not before. That's akin to what I've heard successful writers say: sit at the computer even if you're blanked. You have to be THERE to write.
