So here's the thing.
You see the future event. You know that if you walk there, it's as good as real. But when you ask yourself, if I can just step into that future snapshot as though through a mirror and be at this event having traversed time, would I give up the experience of all that time just to arrive quickly at a happy landmark, you would be a fool to say yes. Even if it meant putting that snapshot in danger of you not getting there, or not getting there in time.
Every moment can count if you make it.
