I am happier when...

I help someone else.
I have accomplished something I can be proud of (large or small). (This was like "emotional weather insurance" for a few days.)
It's sunny out and/or I have a lot of light where I am.
I take occasional breaks just to relax.
I'm watching my kitties do something cute.
I've had a shower, food, and sleep recently.
I'm hearing happy-sounding (usually energetic) music.
I am exercising regularly or I have exercised recently.

What about you?
