There was a long time I had no job security, no options and no education.

If you're unwilling to leave someplace you've outgrown, you will never reach your full potential. To be the best, you have to constantly be challenging yourself, raising the bar, pushing the limits of what you can do. Don't stand still, leap forward.

To be a fighter, you have to be passionate. I have so much passion, it's hard to hold it all in. That passion escapes as tears from my eyes, sweat from my pores, blood from my veins.

The way that I like to fight is I like to paint myself into a corner and so the only way is for me to win.

As an athlete you're taught to be selfish. When I'm training, it's usually all about me.

People say to me all the time, 'You have no fear.' I tell them, 'No, that's not true. I'm scared all the time. You have to have fear in order to have courage. I'm a courageous person because I'm a scared person.'

I'm scared of failure all the time. But not scared enough to stop trying.
