I've officially eliminated the alarm clock from my daily awakening. I discovered a few years ago that if I look at the clock and tell myself that I want to wake up from a nap at a specific time, I would actually wake up at the correct time about 95% of the time. I've extended that to a full night's sleep the past couple weeks, though I haven't been taking note of the current time when I've gotten into bed. All I do is tell myself I want to wake up at 7:02 AM, for example, and I do. I don't really think I'm special, I think anybody could do it.
