The Maroons prop and Melbourne Storm forward, set to come off the bench for the Holden State of Origin's third game, discussed the phone call from Storm's Paul Bunn that diverted his career path.
Glasby was a major figure in the Maroons' series victory in 2017, originally a financial planner in Rockhampton in 2012 after several successful seasons with the CQ Capras; content with his lot when the call came through.
"When I was at the Capras I was settled in Rockhampton and working for a financial planning firm up there," Glasby told NRL.com.
"Paul Bunn, who is the recruitment chief at the Storm, called me at work and it came through on the landline."
Glasby said Bunn offered an opportunity to join Melbourne; but the star prop made sure his stay at Storm would be for a full season.
"I'd looked at doing that for the Broncos in the past but I couldn't do it because I had a good job, but when he said it was full-time I was super excited and jumped at it...but never thought Origin was on the horizon."
Glasby credited Rabbitohs coach Anthony Seibold, a development coach at the Storm at the time for a tip-off to Bunn about him.
Glasby's transformation from a state league player to Origin can be traced to Craig Bellamy's influence and Storm's seniors, shaping his development as a player.
"The standards that are set and you are required to stick to are very high and if you can learn to do that you will go a long way," he said.
"I think I was a good fit for that system and I think for me to get to the level I have it was about doing what I always have and working hard on the little things in my game," he said.
Sending off Billy Slater, Glasby's teammate and Maroons captain, remains a priority for the prop; saying the Queensland legend deserves to finish his career with the club on his own terms.
"Billy has been such a great player for such a long time and I just want him to do whatever he wants to do and if that's [to] go around again, great," Glasby said.
"If he wants to retire, then fantastic as well, he has had an amazing career and everyone is really proud of what he has done. I just want what makes him happy."
