Amir Khan believes he is just approaching his peak as he prepares to defend his WBA and IBF light-welterweight titles against Lamont Peterson.
And the Bolton boxer says that he expects to retire earlier than most because he has already achieved so much.
Khan, who won an Olympic silver medal at the age of 17, has bounced back from a shocking knockout defeat to Breidis Prescott to become world champion.
But he knows the biggest fights are ahead of him as he continues to build his ring legacy.
"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," he said.
"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."
Khan insists he remains grounded despite his success and is not looking too far ahead.
"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."
