This is how I began to discover that, if I put the work in before going to bed, I often had a little creative idea overnight, which fixed whatever problem it was that I was trying to deal with. It was like a gift, a reward for all my wrestling with the puzzle. I began to think to myself, “It can only be that while I’m asleep, my mind goes on working at the problem so that it can give me the answer in the morning.”
