At the end of the season, I normally get some time off training and can go on vacation and enjoy myself.

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

I can't watch a [Floyd] Mayweather fight. I don't find it exciting. I used to watch boxing in the [Michael] Tyson era when it was exciting. Now it's all bob and weave, a punch here and there. It is not entertaining.

You have to get to the worst to get better.

Don't think about the start of the race, think about the ending.

If you feel strongly about something and you want to voice your opinion, I feel it's your right, so, that's how I look at it because that's how life is.

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