"I tried to back out of representative golf about 15 years ago, and I did for two seasons but I really missed it.
"I honestly just got sick of it, I debuted for northland at 18 and here I am at 57 ... I lost that fire.
"[But now], by having had a taste of it, it's a slightly different feel than provincial golf so I plan on being available [for New Zealand seniors] in future."
Billington's attitude is everything that competitive and representative sport is all about, winning, and he is taking that to the national senior team.
"I don't do failing very well," Billington commented. "I really enjoy the competitive environment when you go away and compete [with the seniors]. I enjoy that but you've got to have a bit of game too, because you don't want to turn up and fail.
"You have your own level and if you don't achieve it and you don't get it as far as I'm concerned you've failed.
"There's a big difference between losing and getting beaten, I don't mind getting beaten but I hate losing. Losing when you play badly doesn't sit good with me."
Billington added that it was refreshing to see players like Kadin Neho coming through the ranks in Northland.
He said Neho was a genuine nice guy, and that he could play.
"It's nice to see some of the guys come through," he said of the up-and-coming Northland golfers.
"Golf is a pretty selfish sport, it doesn't really involve much team work and you see some brats come up through it but Kadin's not like that - he's just a really nice guy."
