Different people have different ideals about happiness. And of course happiness is a very important thing in our life. Some consider more money more happiness. But I do not think so. Money can buy medicine and can not buy health. Money can buy bookes and can not buy knowledge. Money can buy a clock and can not buy the time. And a survey also point out that economic growth did not improve human morale. Some others deem more freedom more happiness. As far as my consider, happiness contains several —my parents health, falling in love and have a child. As everything exist only because its opposite, happiness exists only when pain exists. We can not be happy everyday in our life. We should have an optimistic attitude to our life. We must believe that weeping may linger for the night but joy comes with the morning. Happiness is less a matter of getting what we want than of wanting what we have. In my opinion, if we want be happy in our life we should cherish what we have, have a optimistic attitude and just do what we want.
