Dar's first four rules for living a happy life.

1. We each are responsible for writing our own rules.
2. If someone criticizes you, it says more about them than it does you.
3. No matter how hard you try, you can't make someone understand you when they're not listening.
4. Try not to judge people too harshly when they won't listen; sometimes their own lives demand all of their attention and they can't focus clearly on what you have to say.
