I try to lead by example.

I try to live my life to the best, but I just always preach that you should just work hard and do your best.

If you're the Olympic champion then they have to wait four more years to get you again.

My diet is much better. I eat what I have to. The older you get, the better you get at making sacrifices.

As long as I'm in great shape, nobody beats me, for sure.

For me, time is everything, because from the time you wake up you have to have your heart and soul in this. You have to work through the day, you have to go to the gym, you have to eat, and yet you have to work as fast as possible to get home and get rest before the next day begins again.

If you think about racing too much you may just lose it a little bit.
