''The thing we really think effects you, like if you had a car crash, or you're a paraplegic, or you won the lottery, all these things, that actually is the smallest component of our happiness. It seems like only about 10% of our actual happiness is effected by that. The final part seems to be based on all kinds of actions, intentions, habits that people bring in. That big 40% seems to control a lot of our happiness, and the good news is that, unlike the other stuff, that part really is under our control.''
