Humility is the recognition of your limitations, and it is from this understanding, and this understanding alone, that the drive comes to work hard at overcoming them.

I have no sense of humor about losing

Federer is the No. 1 in tennis, and if I meet him in the Masters Cup, I'll play a world No. 1. It will be difficult, but I' m very young and have nothing to be afraid of.

I'm ambidextrous when I eat. But playing tennis right-handed - I can't do it. I'm clueless.

I'm only superstitious on the tennis court.

The glory is being happy. The glory is not winning here or winning there. The glory is enjoying practicing, enjoy every day, enjoying to work hard, trying to be a better player than before.
