Munster coach Declan Kidney said the pain of past defeats inspired his side to Heineken Cup glory against Biarritz.
Munster celebrate winning the Heineken Cup in Cardiff
The Irish province have lost in two previous finals in 2000 and 2002 but held firm to edge the French champions 23-19 in Cardiff.
"This bunch of guys have had tough experiences over the years but have tried to learn every time they have lost," said Kidney.
"That experience of losing helped them today."
Munster captain Anthony Foley insisted the travelling support of more than 50,000 red-shirted Irishmen was added motivation.
"At times out there it was awesome to see the amount of red," said Foley.
"When Biarritz came back at us the fans never got on our back, they are very knowledgeable. Our crowd wouldn't be silenced today.
"Over the years they've been putting their hands in their pocket to follow us around Europe and it's great that we can give them some silverware. We all just feel like one, that's the big thing about this team."
Foley, who has missed just one of Munster's 77 Heineken Cup games over the last 11 years, added: "I've been in a ground twice when the opposition's captain has lifted the trophy.
"To be the one to go up there and pick up the silverware is a great feeling.
"I felt we deserved it over the year. As a player there is nothing that will ever surpass your first international cap.
"That is the ultimate. But what we achieved today is magnificent. It's a journey which is not over yet - it's just another station on the way.
"We can kick on from here and if we do we can compete for this trophy for a number of years to come."
Man-of-the-match Peter Stringer, who scored Munster's second try with an impudent solo break down the blindside off a close-range scrum, said discipline was the key.
"We waited so long, I can't ask for more than the 100% the guys have given," said the scrum-half.
"It has been a long time, we have worked hard. It was about honesty from one to 22. We are delighted with the win.
"We worked extremely hard in the first half and we tried to produce the same performance in the second.
"But Biarritz had a purple patch. They came at us but we have worked hard on our defence in the last couple of weeks and we held strong in the end. Our discipline proved very good and I think that won us the game."
