Part of my evolution has been to learn how painful most people's childhoods are. They grow up not liking themselves, not loving themselves. Ask people if they were lovable the minute they were born, and watch them sit back and have to think about it. One lady said, 'I suppose so.' That's painful.

If you think about evolution, sleep, at some time, was a dangerous undertaking. You lie down in your cave or shelter, and along comes a predator and has you for dinner. Many creatures do not sleep or sleep while standing so they can escape from dangerous situations.
