I don't hide out. If you build a wall around yourself, it draws people to invade it. Fear is the enemy.

I don't have many walls that I put up.

If people want to put me up on their walls, I'll love it.

I've shut myself inside these walls, and I'm going to be a very lonely old lady if I'm not careful.

Here in America, we don't give in to our fears. We don't build up walls to keep people out.

You have to be young to be able to do things like that. Now I'm more cautious. I'm proud that I was able to do what I did - psychologically it was a great wall to climb - but sometimes I regret it.

I can never be safe; I always try and go against the grain. As soon as I accomplish one thing, I just set a higher goal. That's how I've gotten to where I am.

My wife always says that I function better up on a big wall than I do anywhere else in life.

I've definitely made sure to surround myself with friends who are going to protect me.
