Short on time, large topic so listen up.
Walt Whitman put this idea in a poem, and I quote:
Answer: that you are here
that life exists and identity,
that the powerful play goes on
and you may contribute a verse
That begs the question: What will your verse be?
Will you sing?
Or make babies who grow up to shake our world
What is your ultimate contribution?
Make it with all that is in you.
Make it as only you can make it.
Just make your contribution and perhaps the world will be better.
