It's not that I can't sleep, exactly. It's that I don't want to. There simply are not enough hours in the day for all the things that I want to do.
Play, work, write on the computer. Read. Pluck my eyebrows. Take a call. Make a call. Knit. Worry about loved ones. Plan my future. Change my plans. Try a new recipe. Watch a movie or television show I wouldn't let the kid see. Paint my nails. Scheme new art projects. Finish old art projects. The list goes on and on . . .
I know I need to get more rest. I try to sleep in on weekend mornings. This isn't exactly working. But I'm working on it.
