Despite lifting multiple Premier Leagues, Champions Leagues, and Ballon d'Ors, there are still plenty of people around who criticise the Portuguese star, and he thanks them for helping him prove them wrong.
"[I] use negative people and experiences to motivate [me]. I actually need my haters - they have helped me achieve all I have achieved," Ronaldo said to Coach Magazine.
That said, the winger also made clear his inner-belief as he pushes himself and strives to continue improving.
"I was," he replied when asked who's been the biggest influence on his career.
"My biggest inspiration has always been myself; nobody puts bigger demands on me than me.
"I said I admired [Luis] Figo and Rui Costa, but I never wanted to emulate anybody - I have just always focused on being the best me I can."
Finally, Ronaldo listed some of the toughest opponents he's had over the years, namechecking Lionel Messi and Ashley Cole.
"There is a big mutual respect between myself and Lionel Messi," the winger stated.
"The media like to make out like we have this big rivalry, but we don't. It is not like we are good friends, but there is a mutual respect on both sides.
"Over the years I had some great battles with Ashley Cole, he doesn't give you a second to breathe. He was such a tenacious player, quick, tough in the tackle, when he was at his peak.
"You knew it would never be an easy game."
