I'm a sucker for any inside look at the work habits of creative people. If I'm being honest, I don't think any of us are at the level of creative genius of the folks listed below. But we can learn from this sort of info.
This is an amazing list. Two things struck me. First, how diverse the individuals were when it came to their daily schedule. Can you imagine going to sleep at 6pm so you could get up at 1am to be creative?
The second thing is the hours. All of these people had the same amount of time as you and I. As diverse and disconnected as they might be, they're all still working from the same length of time that you and I have every single morning. You probably need more sleep than Mozart did, but don't forget to make sure every hour of your day counts.
