I have read my share of research on happiness, of course, but I can say that the book by Prof. Sonja Lyubomirsky was still able to surprise me in some ways. The research that she selected to include is quite interesting, although often intuitive. It definitely sparkled my further curiosity and thirst to know more.
The book attempts to answer an important question that has “bothered” humanity for a long time—namely: Why can’t we ever be completely happy? And why do certain things, that we believe will make us happy (a new job, more money, a soul-mate), after we obtain them, don’t give us the satisfaction we expected?
