Do you ever look at people who are successful, healthy, and happy and wonder what their secret is? Why you can't be like that?
True happiness is an "inside job". Look at a happy person's life and you don't see any magic or unicorns. There's nothing in them that isn't also in you. Though external realities can certainly play a role, happiness doesn't spring from what you have, what happens to you, the situation you are in, where you are, or anything else. In fact, if it was easy to be happy, this book would be a very short one!
