I saw the movie Happy last night http://www.thehappymovie.com/
It was a really excellent film about how we create our own happiness.
A couple of interesting points were:

40% of what makes us happy is up to us to create.
Only 10% of happiness is situational having to do with money, status, etc.
The “hedonic loop” of materialism is never ending and does not create happiness.
We quickly forget painful and pleasurable events.

I recommend this film to everyone and especially those who are tired of struggling to find
happiness in things that don’t work.
