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. 

Happiness isn’t always reciprocated with joy because individuals have unique emotional states, personal challenges, or perceptions that influence their reactions. Someone may appreciate your happiness but not feel joy themselves, as it depends on their internal circumstances.
