A lot of people say, "Oh, I get this high from working out." I've never felt that, maybe because I've worked out for so long it's just a norm for me to push super, super hard. I don't feel the euphoria. But at the end, when it's all done, I feel euphoric. I'm like, "Yes, the work is done." You just feel like a glowing feeling inside.

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.

It's amazing when tragedy strikes, how strong you find that you are, and I'd seen other people go through horrible things. And I just thought, "Wow, I would be a complete mess," and then suddenly when it happens, you realize you had more strength than you knew and it helps you to get through.
