So far in my career, I've achieved what I've achieved because I've believed that I could do it. And I've never believed that anyone's better than me, because I think when you start doing that, you've already lost the fight.

When I set my eyes on the gold at the world championships, I was able to maintain that focus that whole day. That's what I aim to do in Rio - my focus is gold, so I can keep in that good state; I can't get too complacent. I can't relax; I can't be content. I need to be 100 per cent switched on.

I could live on fresh bread. My parents, who are Polish, have brought us up on varieties of bread from European bakeries, and I love rye, caraway seed, dark rye... throw in some butter and cheese, and I'm set.

I sleep five or six hours a night, then crash at the weekend. I'm learning to eat properly and exercise. I relax by watching silly sitcoms like 'Scrubs' and 'How I Met Your Mother.'

If you go into a bank or a shop and you want them to believe that you're going to shoot them, that's an acting exercise. If you want to turn to someone else who's as tooled up as you are and persuade them to put their knife down because you'll use your knife, that's an acting exercise. Nine out of 10 delinquents are frustrated actors.

When I exercise, I need to connect to myself and see how I'm feeling at the moment because my mood is constantly changing.

My top three priorities for my first term in Congress are growing our economy; providing for quality, affordable health care; and keeping our nation and communities safe.
