Amir Khan turns 25 today, predicting he will hit his peak in the next year or two before retiring while still a young man.
Khan, who represented Britain as a 17-year-old at the 2004 Olympic Games and won the WBA light-welterweight at just 22, faces Lamont Peterson in Washington this weekend with his sights firmly set on a lucrative move up to welterweight next year.
He is rightly proud of his career so far but hopes to cement his legacy in the next couple of years before bowing out on top.
"I'm only young and I think I've achieved a lot in my career already at this age but I feel I haven't hit my peak yet," said Bolton-born Khan.
"I think within the next couple of years I'll achieve my dreams and have some of the super-fights that I want.
"I think I'll peak around 26 years old, have some big super-fights at around that age and probably call it a day early.
"I've done a lot of things early in my career and that probably means I can retire early as well."
First, though, he puts his WBA and IBF belts on the line on Saturday and knows he must negotiate a tricky challenge against local man Peterson at Washington's Convention Center.
"One thing about me is even though I know I've got the tools in my bag I still go into a fight like a challenger and stick to the instructions from my corner," he said.
"I go into a fight not thinking I am the best but thinking I'm a normal fighter who just needs to go in there and win the fight to take me to the next level. Because if you start thinking you're the best and blowing smoke up your own backside then things can go wrong.
"But I've got a great team around me who help me keep my feet on the ground and that's what it's all about really, just being focused."
Khan (26-1, 18KO wins) has enjoyed most of the media attention heading into the contest despite it being a home fight for Washington native Peterson (29-1-1, 15KO wins).
The bout has added interest due to Peterson's incredible life story - which has seen him rise from homelessness as a child to the verge of world-title glory - but the 27-year-old is happy to fly under the radar.
"I'm okay with him getting most of the attention and being considered the fighter in this fight," said the local man, who lost in his 2009 challenge for Timothy Bradley's WBO title.
"The good thing is at the end of the day, we have to get in the ring. We have to do those 12 rounds if need be.
"I'll get my chance to shine. It's not really a problem with me. I'm okay with it. I'm comfortable where I'm at right now and just happy to have this opportunity to show what I can do.
