I think I can win a slam. That's my main goal, and if I could choose one, then yes, it would have to be Wimbledon. But, honestly, I would take any one of them.

Whoever has played tennis knows the court is pretty big and you always have space to put the ball in.

The grass is a very big challenge for me. There are these low bounces and different movements, which is very difficult, especially for my height and weight. When the surfaces change, and I start to play on grass, I start to feel it in the lower back and the lower hamstring.

I do a lot of biking. I need that mileage and the long-distance stuff because tennis demands it. My fitness trainer is always trying to convince me to do an Ironman. I can probably run the marathon, I can make the 112 miles on the bike, but I will never swim for 2.4 miles. I will die after 100 meters.

I was a ball guy. I played basketball, baseball, football. I excelled in football the most. I played running back, wide receiver, safety, kick returner, punt returner.

For the longest time, I thought I was a boy. I really did. I wore boys' clothes, played tag football.

Well football teams are perhaps easier to control than political parties, I'm sure the Prime Minister would agree with me, but yeah I think every team needs discipline and a sense of self-belief and that's important, that's what leadership's all about.

When my parents were paying for my sport, it wasn't just me out on the ice. Pretty much every dollar my mom made teaching went into my skating.
