Lennox Lewis is confident Ricky Hatton will cope with his second retirement better than he did with his first.
The former two-weight world champion returned to the ring on Saturday after three-and-a-half years away to fight Ukraine's Vyacheslav Senchenko, but his comeback ended with a ninth-round knockdown.
Lewis told BBC Radio Five Live's Sportsweek: "I've always got love for him. I feel he's got a lot of good people around him and I don't think he's going to fail in anything he does. He has to hold his head high."
Hatton immediately announced it would be his last fight and insisted he was at peace with the decision after finding out he no longer had what it takes.
Hatton's struggles since his 2009 defeat by Manny Pacquiao have been well documented, with the 34-year-old battling drink and drug problems and sliding into a depression that left him suicidal.
Hatton is confident he will not return to the bad old days this time and Lewis, the former undisputed heavyweight champion of the world, echoed that sentiment.
Lewis added: "I hope that he came away with some good things because it's very important we have to improve upon ourselves all the time and think positively.
"Hopefully he's learned from all those bad things that happened and he can go forward and lead a better life. I think he should be all right."
Hatton has already made strides into the world of promoting fights as well as opening his own gym in Hyde, where he now trains other fighters.
Lewis expects him to enjoy success in the next phase of his life, and he said: "We step in and we want to be great athletes but every athlete knows there's always a B plan, always something to do after."
