Andy Lee got to the summit of the professional game as a fighter by becoming a middleweight world champion.
But lately the Limerick native has been adjusting to life as a coach and guide to others.
Famously, he played a role in Tyson Fury's coaching team as he defeated Deontay Wilder in a heavyweight rematch earlier this year.
But he has also been coaching Jason Quigley and Paddy Donovan as the Irish fighters make their way in the professional game.
Lee joined RTÉ 2fm's Game On for their latest 'Legends' interview and touched on the challenges of being teacher rather than student.
"It's a big transition and it's a lot of work in a different way," he said.
"Obviously, when you're fighting and training, that's the work.
"But in terms of when I'm training the two lads and even with Tyson Fury, you're constantly thinking about it.
"You do the session and you're constantly analysing the session in your head and thinking about which ways they can improve and what I could have done differently to communicate to them.
"I'm quite fortunate in the sense that I'm still able to display the technique and sometimes you learn more from what you see than from what you're told.
"So if there is something that I can see that they need to make an adjustment [on], I can easily get up in the ring and display it for them in a specific way.
"That's something that has helped me in still being in touch with boxing. But as the fighters have progressed, so have I.
"I'm less than a year now coaching but you just draw on all your experience and constantly thinking about my career, the fights I had, my coaches, how they spoke to me, words they would use, things they taught me and just try to impart that in the best possible way."
He added that the talent and experience Quigley and Donovan already possess has made that transition easier.
In terms of learning lessons and then applying them for the benefit of his fighters, Lee gave the example of one of Donovan's wins when he overpowered an opponent but despite giving everything he still found the knockout elusive.
Donovan would manage a KO in his next fight but in between Lee had analysed the previous fight and experiences from his own career and communicated an important message to his protege.
"There are two ways of stopping somebody in a fight," he explained.
"It's either you hit them with a punch they don't see or you fight at a pace that they can't live at and so they have to check out mentally and physically.
"But with Paddy, he's such a quick, skillful and tricky fighter that if he was creative and not trying to force it and not trying to impress people outside the ring - he's only 21 now and was 20 at the time - that the opportunity will come.
"The less you try, the easier it will be because the opportunity will come and he created the opportunity by throwing feints and giving the guy a small bit of success by letting him land jabs."
Given Fury's deeper experience as a pro, Lee said that coach-fighter partnership was more "collaborative" than with a younger boxer.
"He's got an unbelievable wealth of knowledge. People don't realise this about him but he's like a boxing historian," he said of Fury.
"He can tell you who fought who and how they won the fight back in 1950. He's got an unbelievable brain for boxing and so a lot of the time within the Tyson camp when we were training, we would work in the gym.
"People see him and he's a larger-than-life character but don't be fooled. When he's in the gym working, he's the hardest worker I've seen and takes it very seriously.
"We would do that every day but also when we would come back from the gym, we would talk for hours about boxing, life, training sessions and how they went, what he felt worked and what he's comfortable with."
