Manners is the key thing. Say, for instance, when you're growing up, you're walking down the street, you've got to tell everybody good morning. Everybody. You can't pass one person.

Every season something happens so I programme that in; something will happen.

If I get to be a legend, I've achieved my goal.

Since they came in with the selfie, it's the worst thing. You hardly ever get asked for autographs any more. It's always selfies.

I stopped worrying about the start. The end is what's important.

Track and field was very big when I was growing up.

I know what I can do, so I never doubt myself.
