Tyson Fury has claimed he doesn't need to continue fighting for the money.
The WBC heavyweight champion said he was prepared to retire after his April 23 clash against Dillian Whyte.
Fury will face off against Brixton's Whyte at Wembley Stadium in a fight which could see 100,000 fans in attendance.
The Gypsy King completed his trilogy series against Deontay Wilder by stopping the American in round 11 in October.
Fury, who claims to have earned more than £100million, says he has little motivation to continue.
"The only thing I can gain is money," Fury told BT Sport. "So after this fight I'll have earned over £100million. If I can spend that, I don't deserve any more, do I?
"I know Mike Tyson spent half a billion and Evander Holyfield 400million and all the rest, but I don't live their big flash lifestyles.
"I live in Morecambe, in Lancashire. It's cheap there. I don't have any big habits like I'm gambling tons of money away. I don't do anything. I can never spend the money I've got.
"I've got stuff I want to do, a lot of opportunities that don't involve me getting brain damage. I've got six kids and a wife. When is enough enough?
"Why do I have to be one of those people who went on too long and got injured? Just had one too many fights and blew it all for what? A few more quid?
"I want to retire on top, unbeaten heavyweight champion of the world. I want to do a Netflix documentary, a Hollywood movie, and be a good husband, father and son.
"Most of all I just want to be happy, and that's probably the hardest thing."
