Nick Kyrgios's emotional and physical Wimbledon rollercoaster ride has taken Australian sport's most polarising personality all the way to the final.
Despite his high hopes, even Kyrgios could scarcely have believed he'd be the first player through to the men's title match nine days after being locked in a tense five-set struggle in his tournament opener with British world number 219 Paul Jubb.
But Rafael Nadal's dramatic withdrawal with an abdominal tear on the eve of what Kyrgios was predicting would be "the most-watched match of all time" has presented the 27-year-old with a dream chance to etch his name in the tennis history books.
Kyrgios will play either top-seeded six-time champion Novak Djokovic or British world number 12 Cameron Norrie on Sunday.
He'll be bidding to join Australian legends Norman Brookes, Gerald Patterson, Jack Crawford, Frank Sedgman, Lew Hoad, Ashley Cooper, Neale Fraser, Rod Laver, Roy Emerson, John Newcombe, Pat Cash and Lleyton Hewitt on the men's singles honour board.
If he becomes Australia's first men's champion since Hewitt in 2002, Kyrgios will also provide a gloriously unexpected and colourful postscript to Ash Barty's unforgettable women's triumph 12 months ago.
Even Kyrgios figured his "ship had sailed" before the enigmatic star — for so long condemned as a wasted talent — at last reached his first maiden grand slam semifinal on Wednesday with victory over Chile's Cristian Garín.
But the prodigiously gifted entertainer from Canberra said after moving into the last four that he was intent — and finally felt ready — to deliver on his rich potential.
"I just feel like I'm more mature," Kyrgios said.
"Earlier in my career if I made a third, fourth or quarterfinals, I'd be on my phone a lot.
"I would be engaging online a lot, would be keen to go out to dinner and explore or just do things to kind of, not necessarily soak in the achievement, but just not conservatively just go back to my house at Wimbledon with my team, put my feet up, get treatment and eat, get good rest.
"I think everyone has the same goal in my team. That's why it's working. We all know what we've come here to do.
"I made it pretty known to them that I wanted to go pretty deep here and possibly even raise the trophy. I've made that pretty known.
"I feel like it's literally just been as simple as get some rest. Like, 'Nick, stay in the house'.
"That's not always been the easiest thing for me over my career."
It was only a few months ago that Kyrgios opened up publicly about his "suicidal thoughts" and wanting to at least quit tennis altogether.
He now appears blissfully content, even with a court date hanging over his head.
Barely 24 hours before his first grand slam quarterfinal in seven and a half years on Wednesday, Kyrgios was summonsed to face a Canberra court over an assault allegation believed to involve ex-girlfriend Chiara Passari.
Kyrgios is ploughing ahead in pursuit of Wimbledon glory, saying after years of anxiety he is now comfortable in his own skin.
"I feel as if, just with anything these days, people are so afraid to just open up on how they're feeling," Kyrgios said.
"For me, it was mental health, obviously. I personally didn't think that Nick Kyrgios was able to feel how I was feeling years ago, obviously with the dark thoughts, the self-harm.
"If I wasn't Nick Kyrgios, I would have opened up about it a lot sooner.
"I feel like if people anonymously told you how they felt, they would do it a lot. People would open up a lot more.
"I mean, I wanted to be the ambassador for people to just be themselves no matter who you are, be comfortable in your own skin, believe in yourself.
"I don't want people to hide anymore. It's okay to be what colour you are, whatever. Just be yourself."
On Sunday, Nick Kyrgios being himself could suddenly be Australia's 16th Wimbledon men's singles champion.
