In a candid interview with the Australian No.1, Lee revealed her lofty career ambitions after finally breaking through to land her maiden major last year.
So long the best female golfer on the planet without a major, Lee's victory at the Evian Championship in France in July has released the shackles and sent the 26-year-old's belief soaring.
"It's really been on the back of my mind for quite a long time and just to be able to be called a major champion gives me a really great feeling," Lee told AAP.
"It really was a monkey off my back and it does let me play with a little bit more freedom because before I felt 'oh, am I ever going to win a major?'
"But then I won and it just gave me a little bit more of that reassurance that I could.
"So internally you have a little bit of a different sort of confidence, like in your swing and the way you're hitting it."
Ever the perfectionist, now Lee is intent on taking her game to new levels in pursuit of a place among the all-time greats.
"Having won Evian, I have a little bit more motivation to win every other major because my ultimate goal is to be in the Hall of Fame," the world No.7 and one-time No.2 said.
"So I can keep moving forward and use this as motivation to win the next major, because winning a major is like really different to winning regular tournament.
"Just the feeling that you get is totally different."
This week's LPGA event in Singapore isn't quite one of the women's five majors but it's close, regarded as "Asia's major".
The depth in the field is phenomenal, with just about every big name in the world gathering at Sentosa Golf Club.
That includes Lee's in-form fellow West Australian Hannah Green.
Green tees off on Thursday chasing a third title from as many events after taking out the Vic Open and then becoming the first woman to win a 72-hole mixed gender tournament on any of the world's leading tours with a runaway four-shot TPS Murray River victory.
Lee believes women's golf has never been stronger.
"I feel like our tour's just getting younger and younger. Everybody's so good and our tour is so global and the younger kids, they're so fearless," she said.
"The depth of our tour is only going to get better and better. The girls coming through just seem to be hungry to be top golfers.
"Maybe with everyone at the top being so good, everybody behind has found motivation to be better.
"So we're bound to just get better and better."
