Relaxed Spieth is big business on Australian Open return Golf Adam Pengilly   Maybe a text exchange with Tiger Woods. Or a few messages from a music megastar. They're about the only times Jordan Spieth, pictured, takes time to ponder how far - and more importantly how fast - he, as world No.1, has come. 
Nothing seems to faze him down the stretch on a Sunday afternoon.
But the man who sauntered back into Sydney, the scene of his Australian Open triumph 12 months ago, which started his ascent to the top of the charts, is certainly big business now.
"A few years ago I was sitting in a high school classroom and now we're here," said Spieth after cramming in nine holes on Monday at the Australian Golf Club, the scene of an exquisite final-day 63 last year.
"For the most part when I'm at the course, it feels normal, which is what's most important to me. A lot of the times off the course I'll sit back and, whether I'm trading texts with a music star or Tiger - whoever - you sit there and say, 'wow, this is actually kind of crazy when you think about it'."
Spieth's first appearance in front of the Australian media was carefully stage-managed for Under Armour.
The apparel giant has NBA MVP Stephen Curry, NFL MVP Tom Brady and MLB MVP Bryce Harper on its books.
Like Rory McIlroy before him, Spieth arrived in Australia last year as potentially the next big thing and returns having been christened exactly that.
Yet it is something other than his US Masters and US Open successes which make the 23-year-old so likeable.
At least to Australian fans.
It was only a small "thumbs up" as the previously major-tortured Jason Day made a putt from another postcode and a simple tap-in on his next stroke during a watershed US PGA win with the American in tow.
In the most intense of environments it was the most revealing of gestures.
There is a sportsman there too.
"Here in Oz the people remind me a lot of home in Texas, they're nice genuine people looking out for others," Spieth said.
"We love coming over here ... it's very different with the style and vibe, but at the same time you have the same genuine people we're used to and that's what we enjoy.
You don't necessarily get that everywhere else so that's cool."
Day might not be here - he has skipped the tournament for the birth of his second child Lucy earlier this month - but he will be back.
Rivalry? Spieth likes to think it is friendly, but there is no doubt the new generation of 20-some- things will be back creating waves again next year.
