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 garden patch, or a redeemed social condition;
To know even one life has breathed easier because you have lived.
This is to have succeeded.
