For a decade he has been trying to land that coveted Green Jacket to satisfy a set that currently includes trophies from two US PGA Championships (2012 and 2014), The Open (2014) and US Open (2011).

The Masters is the one that he most wants, but he is also driven by the thought of winning an away Ryder Cup - for the second time - and adding Olympic glory. In fact, give him those and his appetite for golfing success would be finally sated.

"Winning the Masters, winning an Olympic medal and another away Ryder Cup, they are my three goals for the rest of my career," McIlroy told BBC Sport.

Of course, this former Olympic sceptic has to wait for the Los Angeles Games in 2028 - perhaps his last realistic opportunity to grab a medal - but the other two objectives are firmly in his sights for this year.

So, as he starts his 2025 PGA Tour season at Pebble Beach this week, McIlroy is tailoring everything to be in prime form when he tees it up at Augusta on the second Thursday of April.

"I've realised that all I can control is myself," he said. "What's right for me right now is to fully focus on myself and to get the best out of myself and get back to winning the biggest tournaments in the world.

"I've been agonisingly close for the past few years, without being able to get it done and that that is the main focus of this year."

The fact that it is more than a decade since he last added to his list of major victories is one of the most startling statistics in the modern game.

He has achieved pretty much everything else, including winning the prestigious Players Championship in 2019 which was in the days when all of the world's best were competing at Sawgrass for the PGA Tour's flagship title.

But the Players is not a major. His slimmed down 2025 schedule, playing more sparingly in the US, is designed to glean success in the big four events that ultimately define careers.

"All of my practice, all of my prep, even the tournaments that I'm playing, it's all geared towards being ready for those four events," McIlroy said.

"Augusta is Augusta. I've gone through my stats and there are a couple of things that were pointed out to me that I could definitely get better at - certain little shots around the greens."

He famously blew a four-shot final-round lead with a ruinous 80 at the 2011 Masters and he was runner-up without truly contending in 2022. He faded tamely when in the final pairing with champion Patrick Reed in 2018 in another of his four top-five Augusta finishes.

Some observers believe the home of the first major of the year is made for McIlroy's powerful game, but it has a way of finding him out technically and temperamentally.

The same cannot be said of the venue for the year's second major, Quail Hollow, which will stage the US PGA Championship in May. McIlroy won his first PGA Tour title there 15 years ago and his most recent victory on the US circuit came at the same North Carolina layout only last May.

"At Quail Hollow I've played some great golf," he said. "I've won four times there.

"I went up against Xander Schauffele, who went on to win two majors last year, and played some of my best golf in in that final round."

McIlroy is also looking forward to competing in the US Open on one of the championship's toughest tracks in Pennsylvania this June, despite missing the cut when it was last played there nine years ago.

In the past couple of US Opens he has been runner-up, last year in agonising fashion after blowing a two-shot lead on the closing stretch of holes to let in Bryson DeChambeau at Pinehurst.

"Oakmont is a place that I think I will relish more as a US Open test now than I did back in 2016," said McIlroy, who has finished top nine in the past six editions of traditionally the toughest major.

"I feel like I've become a very, very good US Open player and I've got the patience and the discipline and the mindset to excel."

The year ahead could hardly be more exciting for McIlroy, with The Open being played at Royal Portrush in his native Northern Ireland. When the Antrim links returned to the rota in 2019 after a 58-year absence, he flopped spectacularly amid the weight of such eager anticipation.

He hit his opening shot out of bounds and carded an eight on the first hole as he slumped to a 79 in round one, and despite a spirited second round of 65 he missed the cut. Unfinished business then.

"I feel like I'm getting a better sense of how I need to approach the week to play well at home with those expectations," McIlroy stated.

"I had a great chance to win the Irish Open at RCD [Royal County Down] last year. I've been through that and I played much better.

"So, you know, all those experiences that I've had will hopefully stand me in good stead for Portrush as well. And I need to turn the near misses into positives rather than negatives."

But there is an admission that goes to the heart of McIlroy's malaise when it comes to trying to succeed in the tournaments he most wants to win. He has never shied from the spotlight, but too frequently it has made him blink.

"I feel like I've always struggled to play at home, none more so than at Portrush in 2019," he said.

"But I'm slowly starting to learn how to overcome the mental fatigue of the week and the expectations and everything else, and try to protect myself in my own little cocoon and go about my business.

"People will argue maybe I'm a slow learner, but at least I'm learning and I'm moving forward."

So a Masters itch still to be scratched, a PGA at his happiest hunting ground in America and a home Open Championship are on the horizon.

And then there is the chance to do something extraordinary in Luke Donald's European Ryder Cup team at Bethpage in New York this September.

"You have heard me say this so many times, but one of the greatest achievements in the game right now is to win an away Ryder Cup and we have an opportunity to do that this year," he said.

"I think there's one thing holding serve at home, which we've been able to do quite consistently. It's a huge task [away from home].

"It's a very strong American team, a very partisan crowd. But we've got a wonderful captain and we're going to have a wonderful team and we're relishing the challenge."

Whisper it, but 2025 could be quite the year.
