"Wayne Gretzky once said “skate where the puck is going, not where it’s been”"
No, no he did not. Steve Jobs said that Wayne Gretzky said "skate where the puck is going, not where it's been". However, I'm sure one day Wayne Gretzky will quote Steve Jobs saying that he once said that you must skate to where the puck is going, not where it's been. That day will be quite awesome.
On that note, what happens when the puck goes past its original position, as inevitably happens in a game of hockey? What does Wayne Gretzky do then? Ignore it?
