This really lightens/enlightens things up on the question:
“What is the purpose of life?”
 
The purpose of your life experience is the joyful expansion that comes from the new ideas that are born within you. The expansion part of that is inevitable. The joyous part is about how well you are keeping up with the expansion.
—Abraham-Hicks
Another perspective…”Focus on your ‘nature’ instead of your ‘purpose’.” Your purpose may include being a parent, but your nature, which is your ‘authentic’ nature is to be a healing force or to experience all aspects and ways of freedom and liberation. Do you see the difference?

So your purpose is to explore and live your true, authentic nature…whatever that is!
