I love this idea!
I have a history of ups and downs. When I am up I get a little lazy in maintaining it so I end up down again fighting my way back. I do almost all of the things mentioned up until now. Getting outdoors does a lot for me. Fresh air lifts my spirits faster than anything so, being in the north, I have recently outfitted myself so that I can take a walk in any weather. I took a walk in a snow storm with my dog and my camera. The sun is good (and bad) and it is outside, a vitamin, exercise gets the endorphins going. I also journal. Books are good and TV is bad for me-except for Gray's...tonight!
A big thing for me is getting enough sleep. Being rested is huge for me.
Let me say again that I love this idea. I have a journaling software that I love. I think I will add a catagory that is JT's owner's manual.

Thx!
