I realized walking one day when I was 14 that I had become obsessedly controled by my wristwatch. I couldn't stop checking it, I had to know what time it "was". In that flash of realization, I removed my watch and hurled it into a snowbank. I've not worn one since. I'm always where I need to be when I need to be there. Clocks are everywhere if you really need to know, but usually I find if something changes my timing there's a gift in it.
A circle of friends I once ran with and I had a greeting we used with one another which consisted of presenting your open hands palms up saying "no weapon" then palms down saying "no watch". I always kinda liked it, changes your brain.
