Tommy O'Brien ranked his two-try showing in Ireland's supberb 43-21 victory over Scotland is the "highlight" of his career.
The 27-year-old Leinster wing won his ninth cap and scored two late tries as Ireland wrapped up the Triple Crown.
"I think it has to be the highlight," said O'Brien, who was left out of the team to play Wales just a fortnight after a try-scoring appearance in the win over England.
"That was my Six Nations debut at home. I made my Six Nations debut against France, which obviously didn't go the way we wanted, but to have the rest of the tournament to build and finish on a high is pretty special.
"Yeah, [missing the Wales game added motivation] for sure. Obviously, any chance you get to wear the Irish jersey, you want it.
"I was disappointed to miss out last week, but it's the nature of this squad is there's strength in depth."
O'Brien was among 11 players that head coach Andy Farrell handed Six Nations debuts to in the championship.
"I think it's something we've done really well this Six Nations, a lot of guys have put their hand up that maybe wouldn't have been seen as front-line players, like Tom O'Toole switching sides, has been unbelievable for us, Jeremy Loughman as well, there's loads of guys," he added.
"So, we just talked about how important that is to get exposure to these important games for the whole squad."
O'Brien's second try (above) came after Scotland lost possession while running the ball from deep. The 27-year-old looked up and saw he was in a race with Scotland first centre Sione Tuipulotu and his score gave the Irish crowd one last cheer after what was an almost complete performance.
"It's an awesome way to finish," he said.
"I think everyone was pretty much out on their feet, but it's kind of a testament to the group that that's how we wanted to finish on a high.
"We kind of had the result sorted, but no one wanted to finish by conceding a try and I think that's a pretty big statement to the group."
O'Brien has had to deal with a number of injuries and set-backs in his career and was thankful to be able to enjoy the good days.
"There was definitely times where I doubted was it going to happen, I always had belief in my ability," he added.
"It was just a case of if my body would play ball.
"So thankfully for the last year and a half, I've managed to keep it in good nick and get a run. It's such an important thing in rugby, is getting a run of games.
"You get a bit of confidence, you get a bit of exposure and thankfully I've got a good result out of it today.
"I think it's something I try to say to myself when I'm running out every time in the tunnel.
"Just saying, 'this is what you dreamed of, this is what all those hard days of rehabbing on your own, this is what it's all for and this is what makes it all worth it'."
With the Triple Crown sealed, O'Brien and his team-mates will watch France against England in the 8.10pm kick-off and hope Les Bleus slip up to give Ireland a shot at the Six Nations title.
"I guess we're just delighted ourselves," he said.
"We've done what we can control.
"We've gotten the five points and now it's up to England to do a favour for us."
