The point about working is not to produce great stuff all the time, but to remain ready for when you can.
There’s no point in saying, "I don’t have an idea today, so I’ll just smoke some drugs." You should stay alert for the moment when a number of things are just ready to collide with one another.
A lot of factors go toward creating a work: technological considerations that suddenly are a little exciting to you, some feeling or mood, a nice day, you just had a talk with a friend. All sorts of things will coincide - and that moment doesn’t last for long. It’s like things in orbit; they’ll move away again.Brian Eno
