To often we view success by material possessions, Ralph Emerson gives a good description here of how success should be measured.

"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 even one life has breathed easier because you have lived. This is to have succeeded. "
