Happiness is a positive emotion, pleasure, or contentment. It tends to be episodic and reactive, arising from enjoyable experiences, satisfying desires, or reaching short-term goals. I am "happy" watching Netflix (smile). I am not happy on a long vacation with screaming children (frown). If you were to optimize for smile - frown, you would do more Netflix, less children. In fact childless people report themselves much happier than people with children.
