I got this from Janice the other day. I love it! It refreshes my spirits, during an especially hairy week of teaching.
Success: to laugh often and much; to win the respect of intelligent people and affection of children; to earn the appreciation of honest critics and endure the betrayal of friends; to appreciate beauty; to find the best in others; to leave the world a bit better place, whether by a healthy child, a garden patch or a redeemed social condition; to know even one life has breathed easier because you have lived. This is to have succeeded.
Ralph Waldo Emerson
