Training is very tough. I probably hurt and get out of breath more in training because in matches, you can hit an ace, then have 25 seconds off. In training, you're doing drills constantly.

My training has always been a priority; whatever needs to be done will get done first before anything else. Social life will come after that. I still love being around friends and family, but with all the travelling overseas, it makes it very tough to fit in.

You learn more doing than doing training.

The tennis calendar is incredibly long, so it's normal to go through ups and downs, and you want to keep the ups as long as possible and the downs as short as possible. You have to be realistic with what you're doing.

I don't get complacent, because I know if you slack off, you're going to be found out. This is international boxing, and every fight is a tough fight.

There were always fistfights. You would hear, 'He hit me,' constantly.
