Sleeping is like meditation: it's good to rest the body but also to shut the mind down for a bit.

This is boxing, not tennis. Everyone likes a bit of rivalry, it makes for a good fight.

The mental is more important than the physical. You know, that voice in your head telling you to give up if it gets tough. That's my main opponent - making sure that if your body wants to stop, your mind won't let you.

From the neck up is where you win or lose the battle. It's the art of war. You have to lock yourself in and strategise your mindset. That's why boxers go to training camps: to shut down the noise and really zone in.

There are two types of warriors: the one that rides through on his horse and tries to slay everyone, and the sniper. I try to be more like the sniper. Bang. Bang. Bang. Break them down, shot by shot.

Rest when you're weary. Refresh and renew yourself, your body, your mind, your spirit. Then get back to work.
