Rory McIlroy admits he is a different man to the one that won at TPC Harding Park five years ago but he does not see any reason why he cannot win a third US PGA Championship title this week in San Francisco.
The Northern Irishman won the 2015 WGC-Match Play over the layout and since then he has turned 30, got married and won a third Race to Dubai title.
The course is also different to how it was back then, and it will feel more different still with health protocols in place and no crowds due to the coronavirus pandemic.
But with happy memories and a liking for a US PGA Championship set-up having lifted the Wanamaker Trophy in 2012 and 2014, McIlroy is feeling confident in the city by the bay.
"I'm hopefully a little wiser, a little more mature, a little more experienced," he said.
"I think back then I had just turned 26. Golf was everything to me, my career and, look, it still is. It's so important and I want to make the most of my time on Tour and everything but there's other things in my life that have happened that are important to me.
"Maybe I've got a little more balance in there. I enjoy other things. I don't get bogged down as much just by golf. There's other things that give me joy and give me pleasure and fulfil me and that's probably the biggest difference."
He added: "It's nice to have some memories around a golf course that you're playing a Major Championship on. It's nice to have those memories and be able to recall some of the shots that you've hit. Hopefully some of that can help me this week and can rekindle that sort of form that helped me win here a few years ago.
"The course is obviously a little different than it was in the Match Play five years ago. The layout and the routing of the course is different. But also they've added some length. There's a few holes that definitely play a lot longer.
"I think the fairways are narrower. They've cut them in a little bit, a couple of different looks. So it is, it's different.
"I've always liked how PGA Championship set-ups have been for me. I think they're fair. You look down a fairway at a PGA Championship and it's sort of the same width the whole way down to the green.
"A lot of courses, they try to pinch it in at 320 and try to handcuff the longer hitters, whereas here the courses just let you play, which I like."
One thing McIlroy has not done in the last five years is add to his impressive tally of four Major Championships, although the 31-year-old is feeling no extra pressure.
"It doesn't keep me up at night and I don't think about it every day," he said. "But when I play these Major Championships, it's something that I'm obviously reminded of.
"I would have liked to have won a couple more Majors in that time frame, and I feel like I've had a couple of decent chances to do so and I just haven't got the job done.
"But the good thing is we have at least three opportunities this year and then hopefully if things normalise going forward, four opportunities. So we're playing seven Major Championships in the next 12 months, basically.
"I've got plenty of opportunities coming my way. I think everyone that stands up here wishes they would have won more and would have played better and all that stuff and I've given myself chances, I just haven't been able to capitalise on them."
