Life is full of disappointments. Youth is the cruelest weapon. Anger is to punish yourself with the mistakes of others; worry is to torture yourself with your own mistakes; regret is to destroy yourself with helpless past events; worry is to scare yourself with virtual risks; loneliness is to imprison yourself in a self-made cell; inferiority is to discredit yourself with the strengths of others. Destiny is not opportunity, but choice. Without many choices, efforts are in vain.
