Nobody grows old merely by living a number of years. We grow old by deserting our ideals. Years may wrinkle the skin, but to give up enthusiasm wrinkles the soul.
The world is a great mirror. It reflects back to you what you are. If you are loving, if you are friendly, if you are helpful, the world will prove loving and friendly and helpful to you. The world is what you are.
Achievement of your happiness is the only moral purpose of your life, and that happiness, not pain or mindless self-indulgence, is the proof of your moral integrity, since it is the proof and the result of your loyalty to the achievement of your values.
