Happiness means different things to different people. For example, some students believe that if they have much money or a large number of possessions, they will be happy. They believe that they will be able to do anything they want to if they have money. Some students think that they should be in good health, and enjoy whatever they like. Many students wish to have much wealth from their parents. In this way they don’t have to work hard, and they can have everything. I don’t agree with the above points. We can’t buy many important things with money, such as health, happiness and knowledge. I value knowledge, which makes me happy, for I can do much for mankind with knowledge. Although different people value happiness differently, my “wealth” of happiness is in my study.
