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.
