One time, I got to go play with lion cubs in Johannesburg. It was amazing. But it's difficult when you're on the road. We're always playing tennis, and there's a lot of pressure. So sometimes you don't get to do the things you'd like to do, because the priority is tennis.

If we live a self-directed, self-motivated, self-centered life, always needing to get our own way, then we're going to be miserable. In fact, many times we believe it's our problems that are making us unhappy when, in reality, it's because we're focused on ourselves!

Boxing is like chess. You encourage your opponent to make mistakes so you can capitalise on it. People think you get in the ring and see the red mist, but it's not about aggression. Avoiding getting knocked out is tactical.
