A Buddhist monk named Daruma was shipwrecked off the coast of Japan, losing both arms and both legs. From that time forward his devotees had to help him with all his necessary functions. He was unable to do anything for himself. And yet, he kept on.
Daruma has become synonymous with bouncing back from adversity and today is remembered in the form of "Daruma dolls"-- curious little egg-shaped dolls that can't be knocked over. They keep rolling back onto their base.
The philosophy behind Daruma is "Fall down seven times, get up eight."
I don't know about you, but for me, music. I find happiness in music. I don't mean stuff like pop, or rock, or dubstep. GOOD songs. Something.... I dunno, "Remember When" by Alan Jackson. "You Raise Me Up" by Josh Groban. Something like that. I find inspiration, dedication, happiness, peace, love, and just emotion in music. I play instruments. I write music. I sing. I listen to music constantly. Music is my life.
I can't top Dodgy's answer, its insanely good; I hope you take away as much as I did from it. Here's what I think: After a particularly bad time in my life, I realized that bad things come in threes (to people who can only count to three*).
Good things happen in ones because you only need one to counteract all the threes you might have recently experienced.
It all depends on who you are. When I feel down, I read. Immersing myself in other's problems always makes me feel better. Maybe I got a low grade on that test, but at least I'm not being followed by an evil count who wants to get my fortune and keeps killing all my guardians and calls me a bookworm right before he tries to kill me. At least my middle name isn't Butthurst. At least my parents weren't killed by a terrible wizard.
