I think there's more stressful periods than others when you're launching new things or going into a new business, or there are many things that can stress you out. Having to let people go, that's stressful. Never fun. But for the most part, I try to manage a schedule that's achievable and try not to make a schedule that's not. And a lot of times, sometimes it becomes a little unmanageable, but in spurts. So I think being able to make an achievable schedule, one that I know I can accomplish.

There have been many frustrating games. I don't there's going to be another one that isn't frustrating. That happens, but that's sport. Otherwise why would there be so much glory in victory.

I'm this overachiever type, I'll just work and work and I'll just do it over and over and over again.

Sport teaches you so much, and you can translate that to other parts of life. But it's definitely a lot of dedication, not just for, you know, myself or the children, but the parents, the family finances, the money that you could be putting toward retirement you're using to buy tennis shoes and restring rackets and tennis lessons. So if you don't make it, then you may never retire. It's definitely a lot of risk.

Tennis is mostly mental. Of course, you must have a lot of physical skill, but you can't play tennis well and not be a good thinker. You win or lose the match before you even go out there.

Serena and I have done some great career planning, and we're playing really at the peak of our tennis right now. I think tennis has been a sport where people play this insane schedule from 14 years old, so of course at 26, it's over. We've really paced ourselves.

You know, growing up my - you know, I came from Compton, Calif., and, you know, it was a place where a lot of people did come out when a lot of people stayed. So I've been able to see the top and the bottom of life, and I think that balances you if you allow it to and if you remember where you came from.
