The great thing is this conversation has made me realise that I'm not working towards the "life purpose" I thought I was supposed to be living, I already am being and living. All this growth I'm doing (and oh my god is there a lot of growth happening right now!) is part of being that purpose. Being an example of what I talk about to others.
So ... my life purpose is to be an example of passion, contribution, love and happiness.
Excellent alliteration, by the way
