Sometimes moments like this don't make any sense when you're in them. It's only later, when you remember back, that they stand as a dividing line between who you were and what you've become...No, the strange thing is you can't say what you felt in the split second that you felt it -- and how that changed everything after -- until the time leads you back to that moment again in the future.

I like the part about how you don't know that a moment is a defining moment until much later when you look back on it and say "that was the moment everything changed."
