What is happiness? The definition of "happiness" in the dictionary is "a feeling of pleasure or satisfaction." To different people, "happiness" has varies meanings. Some people might think making more money could make them pleasure; some people might think having great grades at school could make them satisfying. To me, be happy can be even simpler-- do what I like to do.
