Answer 1

Answer:

Happiness is a state, not a trait; in other words, it isn't a long-lasting, permanent feature or personality trait, but a more fleeting, changeable state. Happiness is equated with feeling pleasure or contentment, meaning that happiness is not to be confused with joy, ecstasy, bliss, or other more intense feelings.
