I'd add to that; try a day/weekend/week without any kind of watch or clock. If I plan on waking at a time, and I KNOW there is no clock to wake me, I nearly always wake on time.

Holidays feel awesome when you just do what your body tells you - eat when you are hungry, go places when you feel like it, sleep when you are ready.

I spent a few weeks in Thailand like this and I felt amazing - I'd wake naturally (feeling great) around dawn, and the days felt huge with plans not tied to times.

Similarly I would have nothing in my pocket except a little paper money. My shack had a combination lock on the door. I'd buy some water when I wanted it, and eat anywhere, leaving the change as a tip. Going down the beach and knowing I had nothing to be stolen, to forget or to go back for (was so hot that I swan in a t-shirt to avoid sunburn) you could just swim off and come to land much further down the beach. Man those were good times!
