I feel like I'm more a fan of tennis rather than it being men's or women's. I enjoy watching doubles as well when it's on. I think that there are certain players that I enjoy watching on the men's and women's side. There's some players that I don't enjoy watching on both sides.

I just enjoy watching tennis. And there's things that you can learn from the men's and the women's game.

Earlier in my career, I used to spend a lot of time practising my tennis on court. Now I've learned that it's better to do just a couple of hours on court and two gym sessions a day. That's what's made me fitter and stronger.

My speed is something that has made a difference to my whole career. When I've felt quick and I'm moving well, it makes a huge difference to my entire game. When I feel a bit slower, I end up doing a lot more defending. When I'm a bit quicker to the ball, I feel I can attack a lot more.

The biggest thing for Asian players to remember is the football style is different in Europe - as is the culture - so they have to accept that. Mentally, they need to be ready and very strong.

I don't feel right unless I have a sport to play or at least a way to work up a sweat.

Formula for success: rise early, work hard, strike oil.

To me, success in the job is setting a vision, guiding an organization through change - which is exactly what I did at Digitas, and I'm very proud of that - and bringing people together and with you. That, to me, is what it takes to be successful.
