What determines happiness?  I only would read the “answers” to this question because on it’s face it seems so ridiculous and I’d be curious.  My baseline belief would be that only you and I can individually determine what happiness is to us.  It’s a deeply personal thing.. or so I thought.  Turns out, Sonja Lyubomirsky has been studying the science behind happiness to learn that 50% of our happiness is actually pre-determined in our DNA.  Basically, some of us are born happier than others.  Assuming that’s true, what about the rest?  What influences our happiness and perhaps more important, are we actually able to influence the other 50%?
