What is success? 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; That is to have succeeded.
Without ambition one starts nothing. Without work one finishes nothing. The prize will not be sent to you. As to methods there may be a million and then some, but the principles are few. The man who grasps principles can successfully select his own methods. The man who tries methods, ignoring principles, is sure to have trouble.
