To laugh oftern and much;
to win the respect of intelligent people and affection of children;
to earn the appriciation of honest critics and endure the betrayal of false friends;
to appriciate 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 lived.
This is to have succeeded.
