Joss Whedon

If you think that happiness means total peace, you will never be happy. Peace comes from the acceptance of the part of you that can never be at peace. That will always be in conflict. If you accept that, everything gets a lot better.

You do not pass through this life. It passes through you. You experience it, you interpret it, you act, and then it is different. That happens constantly. You are changing the world. You always have been.

Don't just be yourself. Be all of yourselves. Don't just live. Be that other thing connected to death. Be life. Live all of your life. Understand it, see it, appreciate it. And have fun.
