I'm not suggesting that the entire nation can't be successful, but there's something to it when you have 150 cable channels and the Internet at your fingertips and video games and all kinds of ADD-addled devices like my iPhone and your BlackBerry and things that keep us busy.

Tennis doesn't encourage any kind of intellectual development.

It does take a great hunger to be successful at anything.

We have a lot of options. America is a great country.
