We were OTing about mindfulness stuff last weekend, and that is one of my things...I'll get 16 buns for this, but I keep a calendar every year that I use as a weather journal...kind of forces you to stop and just observe the sky for a few moments each day..to get in idea of how cloudy it was etc...high, low temps.....
I did it when I was a kid, stopped for awhile when I was a teen and young adult, but picked back up several years ago once I got my life in order.
