I was rooting hard for Charlie last week,

This Week with George Stephanopoulos.

I just love working hard. I love being part of a team; I love working toward a common goal.

I've never been through anything like that before, ... They pushed you so hard. Seven days a week for six or seven hours a day. I think the first episode didn't do justice to the intensity of what everyone went through.

It's a frustrating game because the situations so drastically change at different times over the course of the week, the game, the season. It feels like brain surgery at times.

I think the great part about what I do is that there's a scoreboard. At the end of every week, you know how you did. You know how well you prepared. You know whether you executed your game plan. There's a tangible score.
