It's hard to turn off the brain. My wife has given up on asking me if I'm done working, knowing that there is always something more on my to-do list.

What I work to avoid is getting stressed about it. I know that stress is a choice, something I create, but it still takes some concentration to get past the thoughts that lead to sleeplessness.

Part of it is planning, part is organization and part is just relaxing, knowing that I've probably committed to more than I should, and that's okay because stretching is a good way to go.
