1. Put on "Such A Lovely Thing" from DeVotchKa's
How It Ends and dance around to it. Or "Just A Ride" by Jem, or "Sing Sing Sing" by the Benny Goodman Orchestra, or "Skokiaan" by Louis Armstrong off of his
All-Time Greatest Hits CD. Just be sure to dance.
2. Mass-text all of your friends and tell them that you love them. Then watch the replies roll in.
3. Get out! Go for a walk, a run, a bicycle ride, a hike, whatever, but get out of your little enclosed space.
4. Write a card or a letter (by hand) to someone you haven't heard from in a long time, and mail it to them. Be sure to let them know they're in your thoughts, especially if it's been awhile.
5. Bring flowers to someone. Especially a stranger or someone who could really use a lift in their day.
6. Make an online donation to a conservation trust. A few really good ones:
http://www.lionconservation.org
http://www.wildlifedirect.org
http://www.SaveOurSeas.org
http://www.seashepherd.org
Alternately, offset your carbon footprint by calculating it and donating automatically here:

7. Make amends...with yourself, with others, with whatever higher power you feel exists, with whatever you need to. Unload some of that guilt you've been hauling around, however you can.
8. Organize a "Free Hugs" campaign with friends (see the original video that spawned the Free Hugs movement on YouTube at http://www.youtube.com/watch?v=vr3x_RRJdd4) and/or family members, community members, for no reason. Just go do it. Nothing has ever made me feel better than the Free Hugs campaign my friends and I staged last year at the Boulder Fall Festival.
9. When you're at the gas station, offer to fill someone else's car up for them. While it's filling, wash their front and rear windshields. They'll be blown away, and you'll feel uplifted.
10. Smile. Smiling makes everything better, no matter what.
