There is no substitute for sleep.
Working on projects is fun. If I’m writing music I like to stay up late. The later the hour the more noise I want to make.
But if I’m writing, I like to get up when the sun does and sit in front of a sunny window and drink espresso and eat croissants.
When I’m overtired my mouth hurts. It’s like the orange oil light in a twenty year old car, telling you it’s time to have a check up and refill the tank.
