Be happy in what you do. Be respectful of yourself. Do good works for others, and the goodness will come back to you and make you a better person. I think that's what happiness is all about.
If I'm astonished by what I've done, then I know I've been somewhere in the making of it but not during the making of it. Only after the fact. If I'm not astonished, then I've failed in the making of it.
