Joy increases as you give it, and diminishes as you try to keep it for yourself. In giving it, you will accumulate a deposit of joy greater than you ever believed possible.
Whatever course you have chosen for yourself, it will not be a chore but an adventure if you bring to it a sense of the glory of striving ... if your sights are set far above the merely secure and mediocre.
My creed is this: Happiness is the only good. The place to be happy is here. The time to be happy is now. The way to be happy is to help make others so.
