Before I read the article I just think happines is a kind of feeling which can make people happy. Actually I never think about the factors of happiness and I always think money is the most important factor of happiness.However by reading the article, I know a lot of factor of happiness such as wealth, goals, relationship,faith and so on.Also according the researcher's research I mention that actually more money not equal to the happiness.Anyway by studying this unit I have a new defenation of happiness.
