According to Nobel Prize-winning psychologist Daniel Kahneman, money does not buy you happiness, but lack of money certainly buys you misery. It is based on the survey about ''life satisfaction'' The other survey also says living in countryside makes you happier than living in city. Giving a gift to someone is important to make you happy as well. It is approved by the psychologist from the University of British Colombia. The last thing that makes you happy is laughing. Try to hold a pencil between your teeth because it reminds your muscles what it feels like to smile!
