It's advice I think that we should all follow. Never, ever, ever live the same day twice. If we do, what's the point? To go back and start repeating things we've done already? This might be an odd analogy, but think of an amusement park. You start off, and there are a ton of rides. At first, it's sick, there are SO many things to go on. But then you get to know the park, and you realize you've been on most of the rides. It doesn't peak your interest like it did before. And then you're waiting in lines for hours on end for things you've already done, already experienced. Eventually, there's no longer an more incentive to even go to the park at all anymore.
