Here is an interesting experiment, to determine if you are sleeping too much (tying your mental alertness to "clock time"):
remove all visible clocks in your bedroom.
With this experiment: I find myself waking after about six hours of sleep, alert and ready to meet the day.
My belief is that if we awake and look at the clock: our mind might convince us that we are tired/simply based on the time. This is similar to eating when we are truly hungry vs. on clock-time.
Moving away from clock-time, I believe, is a way to become more conscious as it removes our automatic responses/behaviors.
Let me know of your experience with this experiment.
Be your own hero!
