Watching a rerun of any sports game is really interesting. You already know the outcome…but the players and the people in attendance don’t.
The people who were there didn’t know the outcome are carrying huge tension and anxiety. But you just get to enjoy it because you already know how it ends.
The tension is only worth the trouble as a means of entertainment (the fans)…or if the tension can effect the outcome for the better (the players).
Taking it out of the metaphor and putting into real life…
The trap is when we have the tension but can’t effect the outcome and in no way is it entertaining but we decide to keep it on our shoulders anyway.
