Or any day off. For a day only. Don't set alarm to wake up. Wake up naturally. Try not to glance at the clock the whole day. (And no cheating with alerts from smart phone!) No agendas; no schedules; no plans. Listen to your body.
Hungry eat. See? Do we need the clock to tell us when to eat?
Tired rest. Or take a nap.
Feel like reading read. Feel like watching TV watch (cannot look at TV schedule and clock).
Do anything without being a slave to the clock.
End of day, sleepy sleep.
The next day, see if you are rested or tired.
If it works for you, now you know a technique to rest your mind, body, and soul.
