Wayne Rooney regrets the way he prepared for the last European Championships, making the England captain all the more determined to ensure his teammates do not go astray next summer.
Saturday's 6-0 defeat of San Marino secured the Three Lions' place in France next year, when the 29-year-old is set to appear in his sixth major championships.
Unlike previous tournaments, though, Rooney will this time approach it not only as star man but the vastly-experienced leader of the group.
Such responsibility has heightened the forward's desire to make Euro 2016 a competition to remember and ensure that England do not flounder like at last year's World Cup.
"The training camps have been right," Rooney said when asked what has gone wrong in the past.
"The senior lads will sit down with the manager and the staff organising the tournament to work out what we can do better.
"I know, personally, when I was suspended before the Euros I went away on holiday which looking back I regret.
"I'll certainly get my part right this time and, as a team, we will all be building to being successful."
The break Rooney refers to was a trip to Las Vegas before the 2012 edition in Poland and Ukraine, which he was suspended for the start of.
"At the time I thought it was no problem and now I know I obviously shouldn't have done it," he said, candidly. "It's flights and jet-lag.
"I was there with my family, but flying so far it takes a while to get over the jet-lag. Maybe not having a long break between the season finishing is probably the best thing."
Asked whether he will talk to the younger members of the squad about that, Rooney said: "Yeah, we've already discussed that.
"I don't think we'll have that long off before the tournament so the lads won't have the option to go too far."
There seems a real determination from Rooney to now add collective international honours to his individual achievements.
Saturday's early penalty in Serravalle saw him go joint top of England's all-time scoring charts with Sir Bobby Charlton, but his main motivation revolves around bring success to the national team.
"It was my 106th cap and, as much as I love playing for England and scoring goals, there would be nothing better than being successful with England," he said.
"That's all any player wants to do. I'm sure the other lads are no different. It's the ultimate goal and if I don't I'll be disappointed.
"Hopefully the young players in the future can, but it's the ultimate goal for me and that's what I want to do -- be successful with England."
Rooney laughed when asked whether Euro 2016 will be his last tournament -- "I hope not, I still feel fine" -- and was in a jovial mood ahead of Tuesday's qualifier against Switzerland.
The Wembley encounter offers England the chance to extend their 100 percent record in Group E, while giving the 29-year-old a great opportunity to usurp Charlton on home turf.
"It would have been nice in San Marino, but to do it at Wembley would be a lot more special and, hopefully, on Tuesday I can do that," Rooney said.
"It would be great if we could go through the whole campaign winning every game. It's nice to qualify.
"As a team, there are a lot of things we can do and that's what we've been doing already. We will do even more of that."
