Having been a fighter for 25 years, I know how to handle the fear. The fear is there, but I use it to motivate me.
I'm somebody from a little tiny town, who had boxed in leisure centres, and my last fight was in Madison Square Garden against one of the greats. What a great way to finish off.
At the end of your career, you go, 'I'm gonna be able to retire undefeated and be one of the very, very few people in history to do it.' People were saying I should try and get to 50-0, but my number was 46 - that was it. I could have kept trying, but one loss would have spoiled everything.
When it comes to the singing part, I think I missed the boat - the whole family can sing except for me. But they can't fight, so I suppose I've been a bit more successful than them there.
It's not just a trainer - as a man, my dad was unbelievable. Even outside boxing, he was my friend as well. We were boxer and trainer in the gym, but as soon as that bell goes, we'd have a cup of tea, and we'd go on about normal life. We would just leave that bit behind. That's how we kept going.
Ideally, it would be nice if you could earn enough money to kick on from boxing and use the finances to start a business. Realistically, that doesn't happen.
