Happiness means different things to different people. For example, some students believe
that if they have much money, they will be happy. They will be able to do anything they
want to do. Some students are rich with the help of their parents. They don't think money
means happiness. We can't buy some of the things with money, such as health and
knowledge. I love knowledge, which makes me happy. Although different people think of
happiness differently, my happiness comes from my study.
