But the Australian internet sensation, who on Wednesday only half-jokingly revealed his part-time role as Justin Bieber's golf coach, will arrive at Augusta National a PGA Tour winner confident he's got the balance right.
The 26-year-old "boy from Perth" was flooded with high-profile congratulations after holding off world No.1 Scottie Scheffler to break his Tour title duck and win the Houston Open on Sunday.
The likes of Steph Curry and Australia's NBA stars Dyson Daniels and Josh Giddey sent messages, while pop star Bieber FaceTimed Lee to discuss his friend's one-shot victory.
Ahead of the year's first major from next Thursday, Lee revealed the pair had become good mates after exchanging numbers at an event.
Bieber even sends Lee footage of his golf swing, that the Australian critiques and posted a screenshot of their conversation to his 294 million Instagram followers.
"He fanboys over me but obviously I'm fanboying over him," Lee gushed.
"He rips it ... I could say I'm his coach."
It's an example of Lee's standing in the celebrity world, powered by social media, that he has grown up with and now embracing after becoming Australia's new No.1, ranked 22 in the world.
"You've got to back it up and that's why people don't do it," Lee, known as 'The Chef', said of his social media presence that's earnt him a cult following.
"There's a lot of 'all talk and no show' and I felt like I kind of got to that stage.
"Where there was a lot of talk, but not as good as golf that I could do.
"I needed, not a reality check, but a kick in the butt, to get a win or good finish. So I'm glad that happened."
Lee is being harsh on himself given the 2025 season had already netted four top-20 Tour finishes in his first six events before his Houston triumph.
A 20th place at The Players Championship early last month stung though, given he shared the lead at the halfway point.
"Something clicked in my head then ... that was a big part of why I did win," he said of his Players fade.
"(I knew) a lot of mental work needed to be done."
Exhausted after holding his nerve down the stretch, Lee enjoyed a dinner at his new Las Vegas home this week with his team and LPGA Tour star sister Minjee before turning his attention to Augusta.
Lee finished 25th last year despite playing with a broken finger suffered in a gym incident, his advice to himself this year being "just don't drop a dumbbell" on his hand this time.
Sure to command a large slice of the huge gallery's attention, Lee knows a green jacket would do wonders as he attempts to leave his mark.
"There's a lot of people who win one tournament ... and not many people remember them," he said.
"So you try to make it a little bit better of a place from posting funny things or cool things.
"And if you can play good golf on top of that, it's best of both worlds."
