Everyone wants to be a world champion, but when you take that first punch it will tell you if you really want to be in this sport or not. For me, there was no doubt.
I'm not going to say I was Britain's greatest ever world champion. I think Joe Calzaghe was the best - although I think I fought a lot better fighters.
For all the success, I never acted any differently. I've always done the same things and I can honestly say I've not changed in the slightest. Sometimes that's the problem.
My fallout with my family was heart-breaking.
Sir Alex Ferguson sent me a letter wishing me good luck before my fight with Floyd Mayweather Jr. He also sent me a United shirt, signed by all of the players. It was a really nice touch and typical of the man who has always made himself available to managers in this country whenever they've needed advice.
There's no better feeling in the world than when I walk in a pub, or a nightclub or a bar or a supermarket, anywhere, and you see people out the corner of your eye and they're going, 'Hey, there's Ricky Hatton. Isn't he a good lad, coming for a pint with us in here?' It makes you feel proud.
Muhammad Ali was the one who started it, winding up his opponents, but he always did it with a twinkle in his eye and a bit of class about him. Mayweather is just insulting from start to finish.
Right from the beginning I wanted to test myself against the best, against real champions.
