The very nature of Milos Raonic quoting billionaire business magnate Warren Buffett speaks volumes about the articulate Canadian.
Not many 24-year-olds earning more money than they know what to do with concern themselves with phrases like "It takes 20 years to build a reputation and five minutes to ruin it", but Raonic is the exception.
When others are behind the wheel of luxury fast cars, Raonic is exploring art galleries.
When others are popping bottles in nightclubs, Raonic is practising.
And when others are channelling their inner LeBron James on PlayStation, Raonic is quoting respected tycoons or thinking about his foundation that helps children with physical disabilities.
In an era of tennis that is increasingly dominated by the off-court lifestyle choices of its stars, Raonic is sometimes viewed as a vanilla personality.
But that's the way he wants it.
"It's all about results, and that's how I want to keep it," he said. "Attention from people outside can be a distraction and I don't want that kind of distraction."
Playing the numbers game that is tennis came second nature to the Montenegrin-born son of two engineers, who grew up with a focus on what he could control, rather than tinkering with the variables.
That mentality often reflected in his tennis, but during the past 18 months he has embarked on a cultural exploration that has opened his eyes to a new way of living - a way of life not many in his chosen profession could relate to.
"I was raised in a household where everything comes down to numbers, but I've taken extensive measures to learn a lot more," Raonic said.
"When it's numbers, everything is in such a controlled atmosphere. In engineering, the numbers give you all the answers. Before, I wasn't really good at accepting things when they went the way I didn't want them to. I've started to like different types of music and different types of art that I never was into before. Even the other day I went up and saw a few nice small galleries up in Fitzroy. I like to see the type of art that isn't really commercial or mainstream. I like to see what the locals have to offer.
"I don't enjoy going out to parties. I don't enjoy those kind of things so this is my escape. Tennis is a big part of my life and I love it, but I have to find a safe haven away from it and I've found that in these kinds of things. I never understood art before. it's amazing because I try to see how it affects me.
"There's no formula to it. It's so opinionated and individual and I've learnt so much more about myself. I've even tried meditation to see if that's something that I could ever like. I've gotten to know myself so much better and I feel that I didn't know myself at all. That's a special feeling because sometimes you think you know everything in the world. It's given me peace in a lot of different things and a different perspective."
Raonic is renowned as the ultimate professional.
Bernard Tomic tells a story about the day a fan strolled on court during a practice session with Raonic in Monte Carlo, demanding the Canadian's signature.
Raonic wouldn't sign it. Not because he is arrogant, but because when it's time to practise, that's all he knows.
For Raonic, that has been his way of thinking since he was a child, often forgoing social events because, as he says, "I want to be the greatest player in the world".
"When you are a teenager you are so dramatic and you don't want to miss out on things," Raonic said.
"You think things are so important and you have a FOMO - a fear of missing out. But I always loved tennis so much, and I wanted to give myself the best possible chance to excel. Those two things never correlated in my mind.
"Missing a party in high school never felt like a sacrifice to me because I've just wanted be great at tennis. I never gave the other stuff much time and I've just created a habit out of it."
Raonic is now, and has been for some time, on the cusp of challenging the sport's premier players.
For some, that would be enough, but for Raonic, every day outside the top echelon of players is wasted time.
"It hasn't been enough for a while now," Raonic admits.
"It depends on how ambitious you are, because the first couple of times you face off against the greatest players in tennis history, it's a great feeling.
"That has its own significant meaning, but you get to a point in time where you don't just want to face off against them, you want to beat them. Now it's not about this being a great opportunity to play them, it's about what can I do to win."
Standing in the way of Raonic and a potential maiden grand slam at the Australian Open is a quarter-final showdown against mentor Novak Djokovic on Wednesday night.
The pair often practise together and Raonic hasn't forgotten the role the word No.1 has played in his career.
"I remember from a young age when I was getting and hoping for wildcards to get into the Canadian Open because my ranking wasn't high enough, I would practise with him and he would have kind words to me and my father," Raonic said.
"It's been great. He's been helpful and I'm grateful for that. He excelled at a young age. I was a late bloomer. I did catch up at 19-20, but I didn't do well as a junior like he did. The gap might only be three or four years in age, but it's bigger because of what points we really broke out at. He gave me a lot of great advice."
Regardless of what transpires on Rod Laver Arena on Wednesday night, Raonic's journey of self exploration shows no signs of slowing.
"The more I learn about myself, the more I realise I don't know. I want to see what I can become."
