Most definitely always been a passion, and always been one of my goals in life as a young person, to have my own business. My dad gave us his entrepreneurial mindset, so that was also ingrained, as well as the tennis. So in a lot of ways it's a part of making my parents proud. I think we all want to make our parents proud, you know?

I don't have time to be negative.

Most of us have grown up, you know, I think there are very few people who have grown up in a home that was, like, super normal. You know, we all have dispositions because maybe you didn't have a mom or you didn't have a dad, maybe your mom died early or maybe mom and dad argued or they got a divorce or who knows? You have issues that maybe you've started younger or maybe you have your own issues because you have them.

I think I've been fortunate to be at the top of the game and in the media for years, and a lot of times, people want to be your friend when you're on the top. You know, there have been times when I've been injured and I never got a phone call. So that's the way it is.

Every Olympics is something special. If you're fortunate enough to play for your country - there's just so much energy. It's truly amazing.

Workout. Lead a balanced life and try to have fun. It's what you make it.

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.
