Happiness is an emotional or affective state that can be individual or shared with other people. Each person has own definition of happiness. For example, some people think that happiness comes from having a lot of money, and some think that happiness can come from simple things such having a friend. Happiness can affect your health, the people around you, and it can make you have a positive life. There are three causes of happiness such as being successful, eating chocolate, and being optimistic.
