Anthony Joshua says he must take his time to earn a world title shot as he does not want to risk becoming a "has been."
Olympic champion Joshua knocked out Jason Gavern in Newcastle on Saturday to make it 11 wins from 11 fights since turning professional.
While he has been tipped Great Britain's biggest heavyweight talent since Lennox Lewis' mantel, Joshua is adamant he has to do it his own way.
"We will be in for a few good nights in the future but there is no point starting to take fights I am not ready for," Joshua told the Sun.
"I've got to build and do it right. I want to be that geezer where they say: 'He did it his way and I'm happy Great Britain have got a good champion'.
"I'd rather that than: 'I told you he is s***, he's just another has-been from Great Britain. We are never going to have a good heavyweight again like Lennox Lewis'. So I am just trying to get it right because it is my time and my era."
Wladimir Klitschko is a known admirer of Joshua's, having invited the Brit to spar ahead of his world title fight with Kubrat Pulev.
Joshua said: "A lot of heavyweights talk a lot of s*** but he is not one of them. So it shows I am heading in the right direction. I will be a major player.
"I am training to be unstoppable and so far I am proving that. Some people say I am not the real deal and some people think they can beat me. It is all a matter of opinion until I prove myself. I have to keep improving until I retire.
"Look at Floyd Mayweather, he is an unbelievable fighter and he still gets criticised. So who am I to start putting myself on a pedestal?"
The 25-year-old is due to fight American Kevin Johnson at London's O2 Arena on May 30, but could yet fight earlier in May too.
