"It's just a mindset of saying, 'now you're here, go and show people why you deserve to be here'."
A 12-month injury recovery to the FIFA World Cup, in just a few weeks.
A deadline-day transfer into a Leicester City debut, in just a few days.
There's no doubt that over the last few months, Harry Souttar has become accustomed to tight turnarounds.
But whether playing the world watching in Al-Wakhra, or under the bright lights of the Premier League in the Midlands of England, he has never once felt thrown into the deep end.
In fact, this constant theme faced with club and country, combatted by a steely mindset of pure belief, is what has allowed Harry to take his domestic and international career to the next level.
Speaking to Socceroos.com.au this week, Souttar shared how he is still buzzing off the back of his dream transfer to England's top flight.
"I've not stopped smiling to be honest with you, I'm just so happy to get it done," Souttar told Socceroos.com.au.
"I always believed that I could play in the Premier League, but obviously it's not until you do it that you'll know.
Obviously I've only played two games - anybody could play well for a couple of games, it's about doing it over the course of a season, or two or three seasons, so I'm not getting carried away."
The way Harry remains grounded, even a couple of days after comprehensively marking the likes of Harry Kane and Son Heung-min during the Foxes' 4-1 win over Tottenham, provides an insight into the unbreakable mentality driving him towards the pinnacle of world football.
It's a frame of mind that saw the centre-half put all fitness doubts aside to return from a serious knee injury and play every minute of Australia's history-making World Cup campaign.
And as he recalls, Souttar always knew he wasn't in Qatar 'just to make up the numbers'.
"It's just a mindset of saying, 'let's go, you've always wanted to play at this level, you've always wanted to play at the World Cup, so now you're here, go and show people why you deserve to be here," he explains.
"I know before the World Cup there was a lot said about, 'he's only played one game, was he going to be fit enough, is he going to do that?'
"So I kind of used that a little bit to go, 'no, I'm going to show everybody that I'm not just here to make up numbers, I'm here to play well and hopefully help the team progress through the next round - which we did."
QUIZ: Can you name every Australian who has appeared in the Premier League?
It's a lesson that Souttar could transfer into clubland just a few weeks later, as Brendan Rodgers handed him his Leicester debut, away to Aston Villa, just days after putting pen to paper on a five-and-a-half-year contract.
"I'd only trained for a couple of days before the Aston Villa game, and the manager said, 'How would you feel about starting?'," Souttar recalls. "And I said, 'Yeah, absolutely. Let's do it.'
"I've worked so hard to get to this point, and always wanted to play in the Premier League, like the World Cup. Now I'm here, you've got to go and show people why you believe you should be here.
It's probably that kind of belief that fuels me."

It was that kind of belief that left Souttar hesitant to accept all of the well-deserved praise he received after returning from the World Cup.
Back in the United Kingdom, Harry's family and friends supported Australia's every step at the tournament, even sending him videos of wild celebrations in pubs after the nation's victories over Tunisia and Denmark.
Yet while naturally grateful for the support, and proud of the role he played, Souttar returned to England still reeling from the tight defeat to Argentina in the Round of 16.
"The support was great and really positive, from teammates and everyone back home," he said.
"But it was a different kind of one for me, because obviously it was still so raw, getting beaten and knocked out.
"Everyone's going to say 'you should be proud of yourself and all that', but it's not until now I look back and think 'yeah, I've got to be proud of myself.' But then I was just still disappointed about how we got beaten.
"But that just fuels the fire for the next three-and-a-half years of qualifying, the Asian Cup, and trying to go that one step further."
Souttar's intense start to life in Leicester continues in the coming weeks, with Premier League fixtures against Manchester United and Arsenal on the way.
He could next pull on the Green and Gold for Australia in March's FIFA Window, when the Subway Socceroos are set to play on home soil for the first time since the FIFA World Cup.
