Serena's always been one of the best, and she will forever be one of the best tennis players in women's tennis.

I think my biggest thing is learning when to hit which serve when, not doing the exact same thing over and over. Because O.K., great, it's 120 miles per hour, but they're standing right there, and they just block it back.

It's one of those things where eventually in your career, it kind of switches from being the young up-and-comer to someone who has had results and the other person is trying to raise their level to play. I think it's a privilege.

Setting a goal, accomplishing it, and feeling good about yourself can help build confidence and perseverance.

Moving forward, I don't really know what I want to do. There is an opportunity within the media for me, but I would like to give back to football in some way if I'm able to help.

I'm a football guy. Baseball, I enjoy it at playoff time.

As a kid, I wanted to be a pro tennis player. I was pretty good; at the tennis academies I attended, I always 'played up' against older age groups.

I had started writing for 'Sports Illustrated,' which was really my dream job growing up. But the writing probably read like I was auditioning to write for 'Letterman' or '70s-era Carson.
