The defition of success, according to Ralph Waldo 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 to 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 garden patch or a redeemed social condition; to know that even one life has breathed easier because you have lived. This is to have succeeded.
