Aristotle:
"Happiness is the meaning and purpose of life, the whole aim and end of human existence."
Positive emotions have an evolutionary reason,that they have a purpose beyond just making us feel good.For example, they help us think beyond what we are thinking right now, broaden our thinking,they help us build relationships, they help us build capacities.
We should work to cultivate positive emotions in ourselves and in those around us, not just as end states in themselves, but also as a means to achieving psychological growth and improved psychological and physical health over time.
What happens when we experience negative emotions is that our consciousness, our thinking narrows and constricts.(Lion, fight or flight)
Downward spiral: a vicious cycle when we go into this narrow and constrict mode.
