Well, I'm afraid you should be out of life to get the answer...
There are ones who seem to live for money, or for happiness, or for love, or for other ones, yes, but I think we all just live and that's all. The most wonderful aspect of life is maybe its mystery itself.
We have one life only, Oliver, so don't waste time/energy/feelings in wondering what's it for or what you're here to do - just live!
