Life is play.
Life generates art.
Or, what we should be aiming for in social change programs is not safety from hardship, but thriving.
These people have very compelling stories for looking at this very similar creative, thriving positive attribute as what we should aim for - or what things are 'for', in the absence of an independently defined purpose in the world.
What are we here for? What is the meaning of life?
Life does not have a 'purpose', it is not 'for' something - it is play. Sit back and enjoy the show.
