If you want to increase your happiness levels, then be altruistic. Help other people. This is one of the interesting findings of research in positive psychology.br br Most people actually think of pleasure, not happiness. They think of the pleasure of eating an ice cream or of going to the movies. But your happiness from these activities looks very much like a square wave. You are happy during the event, but half an hour later it has very little effect on your current state of happiness.br br However, humans are wired for helping others. We get a nice long tail of happiness: Days later, you can close your eyes and get a warm, happy feeling as you remember helping your friend with something that mattered to him or her. Either that or you've just peed yourself.
