You could do something for others--not for you per se, or your family, or your friends--but for others. Choose to be selfless and useful. My entire life turned around when, down in the dregs of medically diagnosed severe depression, I realized that this was what had gone from my life. Acting on this awareness has brought me back to full stride. I need to be useful to feel alive.

For example, look at what Tosa does here. He doesn't get paid. He's done it for years. He serves all of us who use this board. He is very appreciated by most. Why do we appreciate him? Why does he keep doing it, particularly when he has to deal with childish BS like he often does?

I think a lot of it has to do with understanding what it means "to serve." Life in every breath, in every cup of tea, etc.. Good luck.
