Happiness and joy are different emotions that are not always reciprocated because they are different in several ways: 

• Duration
  Happiness is usually a fleeting emotion that’s triggered by a specific moment or event. Joy is a more long-lasting state of being that’s characterized by contentment and satisfaction with life. 

• Choice
  Happiness happens to us, and we don’t choose to feel it. Joy is a choice that we make purposefully. 

• Attitude
  Happiness is typically situational, while joy is more about attitude and how we approach everyday events. 

  Other differences between happiness and joy include:

• Definition
  Happiness is an immediate, in-the-moment experience. Arthur Brooks defines happiness as a combination of enjoyment, satisfaction, and purpose.

Life satisfaction
Research views life satisfaction as more stable and long-lived than happiness. Life satisfaction is an evaluation of one’s life, and it’s influenced by many factors, including relationships, health, and personal development.
