So I believe true happiness is about being at one with something. When you are an integral part of something - there is a reason for you to exist. A purpose, if you will, even though the word purpose is too loaded. The whole, of which you are a part, needs you to be a part. This whole can be anything you want, large or small, as long as it's bigger than yourself. It can be your family, your work of art, your project, or even Universe at large.
