I too am pretty much thinking something all the time. When I go to sleep at night, I think and think and before long my thoughts sort of drift out my control and blossom into dreams.

Because I can't seem to stop the inner dialogue in my head most of the time, I treasure activities that overcome it, like playing music or solving mathematical problems. I once read an essay by Alice Walker about her mother's gardening. She wrote that her mother seemed to be in ecstasy when she had "become all eyes and hands."
