My definition to the happiness
     First , happiness is  a kind of feeling , and it is hard to get an accurate definition.
     Second, happiness is still the freedom to do what you want to do ,meanwhile to refuse to do what you dislike to do . Simple and easy as it sounds , it is very difficult to realize, since there’re so many unfairnesses, pressure and displeasure in our daily life. The reality must push you to do things go against your desire.
     Most times we base our happiness on money and material. However , happiness is not absolute ,it is relative as for different person from psychological, to some extent ,happiness is equal to all human beings,if you have a good mentality, nomatter who you are and what you do ,happiness will always around you.
