Get a dog and walk it often. The dog will make you happy, the exercise will make you feel and sleep better, and you will meet other dog owners who are happy to talk to you about -- dogs!

Volunteer your time to help others. I believe the only way to be truly happy is to help others. Try to treat everyone as if they were part of your extended family.
