Jordi Murphy chose Ireland over trophies when he left Leinster for Ulster.
"I came to a crossroads last year when I knew something had to change," he said.
"Every international player has the ambition to keep playing international rugby.
"When I was left out of the November squad by Joe (Schmidt) last year, I just thought that I probably wasn't playing enough with Leinster.
"I was stuck in a rut and needed a new challenge," he said.
The stale situation at Leinster was caused by the competition in the back row, the conveyor belt churning out international back rows on an annual basis.
"My greatest ambition as an Irish rugby player is to play for Ireland," he stated.
The steps taken by Murphy and Joey Carbery, moving to Munster, could turn a trickle into a flow of Leinstermen out of the province.
"It may start happening more because there's so much quality coming through at such a young age. Maybe it's not the traditional thing to do, for Leinster players to go to Ulster, but I don't see why it can't happen more."
Meanwhile, Munster must move away from the periods of mediocrity that have blighted their inconsistent opening to the PRO14, leading to two losses from four rounds, insisted Peter O'Mahony.
"You can only worry about your process and your performance," he said.
"You'd like to think that if you put in an 80-minute performance with the calibre of players that we've got now, then we should be winning games."
There is nothing better than a good old-fashioned inter-provincial derby to get players into the right head space where mistakes and missed tackles are minimised.
Ulster will travel to Thomond Park on Saturday (KO 7.35, eir Sport) in high spirits from three wins out of four.
It is there Murphy and O'Mahony will meet with more than PRO14 points on the line.
