The secret of success is learning how to use pain and pleasure instead of having pain and pleasure use you. If you do that, you're in control of your life. If you don't, life controls you.
Success is almost totally dependent upon drive and persistence. The extra energy required to make another effort or try another approach is the secret of winning.
A man is the part he plays among his fellows. He is not isolated; he cannot be. His life is made up of the relations he bears to others - is made or marred by those relations, guided by them, judged by them, expressed in them. There is nothing else upon which he can spend his spirit - nothing else that we can see. It is by these he gets his spiritual growth; it is by these we see his character revealed, his purpose, his gifts. A few (men) act as those who have mastered the secrets of a serious art, with deliberate subordination of themselves to the great end and motive of the play. These have "found themselves," and have all the ease of a perfect adjustment.
The stars of midnight shall be dear To her; and she shall lean her ear In many a secret place Where rivulets dance their wayward round, And beauty born of murmuring sound Shall pass into her face.
