The science of happiness -

IF RECENT scientific research on happiness -- and there has been quite a bit -- has proved anything, it's that happiness is not a goal. It's a process. Although our tendency to be happy or not is partly inborn, it's also partly within our control. And, perhaps more surprising, happiness brings success, not the other way around. Though many people think happiness is elusive, scientists have actually pinned it down and know how to get it.
