Martin Seligman was a pioneer in happiness research.
He found that people who pursued the Pleasant Life experienced little happiness, while those who pursued the Meaningful Life and the Engaged Life were very happy.
Seligman describes three kinds of happiness:
1. Pleasant Life –enjoy yourself, eat well, savor life.
Dance for fun
2. Engaged Life–develop a passion and work hard at it, lose yourself in it. Hug a tree
3. Meaningful Life–contribute to the greater good.
