 You are not to do anything to be happy. In fact you have done too much to become unhappy. If you want to be unhappy, do too much. If you want to be happy, allow things, allow things to be. Rest, relax, and be in a let-go. Let go is the secret of life. When you are in a let-go many things, millions of things, start happening. They were already happening but you were never aware.
