Justin Rose would like to have changed how he reached No.1 in the world.
But not when.
Rose felt conflicted when the BMW Championship ended in light rain at Aronimink Golf Club - runner-up to Keegan Bradley after a playoff.
The consolation prize was replacing Dustin Johnson at the top of the world rankings to be just the 22nd golfer to achieve the feat.
"In the moment, we're all about trying to win a golf tournament," Rose said.
"But give me half an hour maybe, and I might be able to say I really enjoyed it."
Reflection came much sooner.
"We did it Dad.... World Number 1. Thank you so much to my family, friends & everybody that has helped me achieve this incredible goal," Rose posted on Twitter.
The words were accompanied by a photo of Rose from Sunday afternoon at Merion Golf Club in 2013 when he hit all the right shots and became a major champion.
He is shown pointing to the sky to acknowledge his father, Ken, who died of leukemia in September 2002.
The day Rose became No.1 in the world was the anniversary of his death, a day the son never forgets.
His ranking was earned over the past two years by a mathematical formula, and over the past 20 years by sheer determination.
"It's boyhood dreams, know what I mean?" Rose said.
"Today is all about the process, and there will be next week to win tournaments.
"But to get to world No. 1 is unbelievable.
"It's something I can say now in my career I've been the best player in the world. I've been to the top of the game."
Rose was a 17-year-old amateur at Royal Birkdale in 1998 who holed out for par on the final hole to tie for fourth.
Over the next year when he turned pro he missed 21 consecutive cuts on the European Tour.
It took him nearly four years before he won for the first time and he went 12 years before winning on the PGA Tour.
He won the US Open by denying Phil Mickelson and added precious gold when he won in golf's return to the Olympics in 2016.
What he won on Monday in Philadelphia was a designation that can't be taken away.
