Can people without passion be happy or successful?

 Authentic happiness is not an intense and brief passion. It is more of a state of well-being characterized by the experience of positive emotions, of medium or low intensity, such as love (not infatuation), fulfillment, harmony, emotional balance, satisfaction, joy, inner peace, etc. Logically, there are passions that also contribute to happiness, such as passion for art, passion for music, passion for sports, passion for work, etc.
