What is the purpose of life?
Well, quite simply, it is to live, to grow, and to eventually die.
The trick of that answer is the definition of the word "grow" and what it pertains to.
It started when you were conceived. Back then the lives of your cells had the purpose of growing you physically and to do their best to grow in the manner necessary to put you together properly. That part wasn't a choice you had control of. It was up to your cells.
And then, at some point, this mass of living cells developed or was given the conscious that is you, to run things, so to speak. Your cells had, still have, and always will have the purpose of developing, growing, and protecting the life they've created. However, at this point YOU are in control of how you grow in nonphysical ways.
As a baby and child you grew by learning about your immediate surroundings, and as you grew so did your universe, your knowledge and experience.
The real questions are:
Do you choose to continue to grow, learn, experience?
What do you choose to do with it?
