Joy is sudden, unexpected, short-lasting, and high-intensity. It’s characterized by a connection with others, or with God, nature, or the universe. Joy expands our thinking and attention, and it fills us with a sense of freedom and abandon. Happiness is stable, longer-lasting, and normally the result of effort. It’s lower in intensity than joy, and more self-focused. With happiness, we feel a sense of being in control. Unlike joy, which is more internal, happiness seems more external and circumstantial.
