Anthony Joshua wants to unify the heavyweight division and says he has only "scratched the surface" of what he can achieve in the ring.
Joshua will make the first defence of his IBF heavyweight crown against Dominic Breazeale on June 25, live and exclusive on Sky Sports Box Office.
The 26-year-old destroyed Charles Martin in two rounds to win the title at The O2 in April and the Olympic gold medallist will now return to the same venue as champion.
However, Joshua, who boasts a perfect record in the professional ranks of 16 straight wins all by knockout, insists he has only just started out in his quest to unify the division.
"I'm pretty satisfied with how far I've come - but I'm nowhere near where I want to be," Joshua said in The Times.
"Everything that's happened since turning pro has been designed to end with me as the unified heavyweight champion of the world.
"I don't feel that I've even scratched the surface of what I can achieve and that's why when I beat Charles Martin I didn't celebrate wildly because I've only had one world title fight, one world title win and one world title belt.
"I want all the belts and I know that there is a lot of work to be done to get there, but I've got a great team behind me and I think I'll get there."
Joshua has been preparing to face his fellow undefeated foe by training with Great Britain's Olympic squad.
"The Olymipcs were unreal and I'm close to the guys that are going to Rio. They will never forget the experience," he said.
"London 2012 laid the foundations for what I've achieved in my pro career.
"All the support I received winning the gold medal has grown and grown since I made my debut at The O2 in 2013, and now we're selling out The O2, time and time again and the fights are getting bigger and bigger."
