happiness,overrated??

 how many books are written about how to be happy?
why are  many people still unhappy?
are these books effective in helping people attain happiness?

the real question here is; what is defines happiness, and is it universal?

maybe just maybe its subjective, maybe it is different for  different people and is represented by different things.

why do we still buy these books, and listen to these shows that offer us tips on how to be happy. how do these people know what happiness is? 

is happiness overrated? blown out of prorpotion.
we might be happy and not even know it, because there is societal definition of happiness.
define your own happiness, make your own happiness.
