Ralph Waldo Emerson was spot on with the definitive answer of "what is success" 150 years ago:

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.
