Emerson

"To laugh often, and much: to win the respect of intelligent people and the affection of children; to earn the appreciation of honest critics and endure the betrayal of false friends; to appreciate beauty; to find the best in others; to leave the world a bit better, whether by a healthy child, a redeemed social condition, or a job well done; to know even one other life has breathed because you lived; this is to have succeeded."
- Ralph Waldo Emerson

I came across this and it really affected me. It's hard to measure success in your twenties, in a world filled with beauty and horror, it put a few things in perspective.
