How many times do you take yourself to the brink of complete collapse? It's not a real fun place to go.
Repercussions are serious and they will take you places.
Before the decathlon I'm constantly trying to convince myself that I want to do this, that I want to take myself to that place where it's going to hurt and things are going to be tough. But that's like anything - you want to give your best.
For so long I wanted to win the gold medal. Then I won. I had to figure out what was the new motivation to take myself to that place again.
You take yourself to a place where you've got absolutely nothing left and then you find out you have to push yourself one more step. That's a tough place to be in.
