Life is like a game of cards. The hand that is dealt you is determinism; the way you play it is free will.
Lost opportunities, lost possibilities, feelings we can never get back. That's part of what it means to be alive. But inside our heads - at least that's where I imagine it - there's a little room where we store those memories. A room like the stacks in this library. And to understand the workings of our own heart we have to keep on making new reference cards. We have to dust things off every once in awhile, let in fresh air, change the water in the flower vases. In other words, you'll live forever in your own private library.
True luck consists not in holding the best of the cards at the table; luckiest is he who knows just when to rise and go home.
We cannot change the cards we are dealt, just how we play the hand.
God does not play dice with the universe; He plays an ineffable game of his own devising, which might be compared, from the perspective of any of the other players, to being involved in an obscure and complex version of poker in a pitch dark room, with blank cards, for infinite stakes, with a dealer who won't tell you the rules, and who smiles all the time.
