The purpose of life (imo) is to discover humanity in yourself and what "the best human" means to you. People get their ideas on "the best human" from many inspired examples. The Buddha, Mohammed the Prophet, Jesus of Nazareth, Julius Caesar, or Jimmy Buffet. Some people need no such idols and can form their own understanding of what it means to be human, but all of these scale.

Your humanity plays into the identity of your family, plays into the identity of your city/town, plays into the identity of your region, plays into the identity of your nation, and at the top is the true meaning of life: the culmination of every dream and desire, the moral fabric of our species, and the embodiment of the only such entity in existence to our knowledge. The purpose of life is to find that, reconcile with it, and use the wisdom you gain in doing so to help shape our species into a happy, healthy, and mature civilization, or die trying.
