How to be Happy?

I found this list of Ten Rules for Happier Living:

1. Give something away.
2. Do a kindness.
3. Give thanks always.
4. Work with vim and vigor
5. Visit elderly and learn from their experience.
6. Look intently into the face of a baby and marvel
7. Laugh often - it's life lubricant.
8. Pray to know God's way.
9. Plan as though you will live forever - you will.
10. Live as though today is your last day on earth.
