Hughie Fury's obsession to become a world champion is such that he has, in his words, "sacrificed" having a normal life. He has never had a girlfriend because of his single-minded focus to train and improve as a boxer.
In a revealing interview with Guardian writer Daniel McRae, Fury, a Traveller like cousin and former world champion Tyson, tells of leaving school at the age of 11, and of his feelings when father and trainer Peter, whom he clearly worships, was twice sent to prison.
Fury, who has just turned 23, fights New Zealander Joseph Parker for the WBO heavyweight world title at the Manchester Arena on Sunday morning NZT. The stakes are high for both men - Parker in his second title defence because he is of course the champion, and for Fury because he has lived only for this moment and the odds are that a loss will mean he won't get such an opportunity again.
"I always said to myself: 'I'm going to be world champion.' I wanted to give my heart and soul to get there. And I've sacrificed everything," Fury told McRae.
"I've had no teenage life, no drinking or having friends. I trained like a professional from a young age. No kid has done what I've done - going alone to train with different people who would shout at me when I showed up at their gyms.
"I've never had a girlfriend. I've always concentrated on boxing because my dad said: 'Women and boxing don't go.' He's a wise man so I've listened and here I am - fighting for the world title in my home town."
Fury tells of a life on the margins in the United Kingdom. The Travelling society are often discriminated against, but what makes his story all the more compelling is that he has never considered doing anything else.
Parker, a 25-year-old, is a well-rounded individual, a talented musician and singer who has done a building apprenticeship, but Fury learned to read and write properly only after leaving school.
Fury said: "After a few months of high school I said: 'What's the point when I already know what I want to achieve?' I knew it would mess with my boxing."
