Both men have described the weekend's win as the best they have ever experienced but the pair are equally keen to ensure it is the springboard to further success and not simply a pleasant memory in years to come.
"That's one of the great days in your rugby life," said Youngs, who starred alongside brother Tom at HQ.
"From my point of view and Tom's, we can finally shut up our dad (Nick), who does like to remind us that he was England scrum-half when they beat New Zealand in 1983!
"This must be seen as the start of a journey but it's important to include all four autumn Tests in that. As a squad we are disappointed that we didn't win four from four.
"We shouldn't have allowed Australia and South Africa to get away from Twickenham with those narrow victories.
"What struck me, reading the programme before the game, was the birth dates of the lads - they are so many from 1987 to 1991, it's ridiculous.
"We have such potential, and so much more to learn, and that's the way to view this result. What was shown is that this England squad came of age, that we fronted up, that we are learning against the best of the best.
"Next it's preparing for the Six Nations, and we have our benchmark - an England record victory over New Zealand."
Robshaw was heavily criticised for his decision making in the defeats to Australia and South Africa but the flanker now has plenty to celebrate at the end of an exhilarating autumn.
But rather than simply sit around and soak up all the glory, Robshaw is determined to ensure he and his troops kick on to even greater things in 2013 and beyond.
"Beating New Zealand may have been the best day of my rugby career so far, but I believe there is so much more to come from this young England side," Robshaw wrote in the Daily Telegraph.
"I told the players as much at the end of the game. I gathered the squad together and told them: "This is our standard now. There is no going back. We must push on from this.
"Yesterday we held a team meeting to set our targets again for when we meet up next month to begin preparations for the Six Nations Championship.
"Stuart Lancaster has been very open about where we want to be in the 2015 World Cup. The key now is that we don't stand still. We have to keep improving if we are going to be serious contenders as the host nation."
