LOL no. Happiness is an emotion, just like anger or sadness.
As for the purpose of life, there isn't one. Or if you're a philosophical nihilist, there isn't an inherent meaning to life, so it's up to each individual to come up with their own.
IMO try not to overthink it. Death still comes one to a customer so you might as well enjoy yourself while making the world a better (or at least not worse) place if you can.
