Your work is to discover your world and then with all your heart give yourself to it.
Oh, yes, even atheists can love Gautama Buddha. He's one of the few religious figures who lived to a ripe old age instead of dying spectacularly, who didn't run about starting wars, and who didn't think all that much of the gods (although that depends on which Buddhist tradition you're listening to - some of them seem to think the Buddha was all about gods, which rather misses the entire point of what he was trying to get across).
If time travel ever comes available, he's one of the historic figures I'll want to sit down with. And I hope that Flower Sermon story is based on actual events. In the meantime, I shall be giving myself to my world with all my heart, because that's damned good advice.
