Sonny Bill Williams

Being a young Kiwi lad, a young Polynesian boy, I was pretty close to my family. But when I moved to Sydney, I went from training twice a week, playing touch footy with my mates, to working full-time as a labourer and training professionally.

You see somebody on a football field make a great, athletic 70-yard run, but the athleticism is immeasurable. It's undoubtedly athletic, but compared to somebody else who did something else, how do you compare it? That's the great part of track and field. It's a test, but with results that you can compare to others.

Leverage is great when it works, and when it doesn't work, it creates a lot of issues. So I think if you limit the amount of leverage that people can borrow, or that banks can borrow, I think you'll find that you'll have a lot less issues going forward.
