Judd Trump should remain focused on claiming his maiden world title, says former winner Ken Doherty.
Trump, 23, moved to the top of the world rankings after securing a place in the International Championship final in China, where he beat Neil Robertson.
The Bristolian impressed in his debut World Championship final in 2011 but lost 18-15 to John Higgins.
And Doherty, who won the title in 1997, told BBC Points West: "It's the one you're going to be remembered for."
He continued: "As a kid, when you're picking up your first cue from Santa, you dream about winning the World Championship and I'm sure Judd is no different.
"He came very close against Higgins a few years ago and had him where he wanted him but missed a blue that, with a little bit more experience, he may not have gone for.
"World number one is nice, don't get me wrong, but I think all the great players have lifted that championship."
Trump received widespread acclaim for his performance in the 2011 final against Higgins, which came four weeks after he had won his first ranking title at the China Open.
He has since gone on to win the UK Championship but could only reach the second round at the Crucible last season.
But after reigning world champion Ronnie O'Sullivan opted to miss the rest of the season for personal reasons, Doherty believes Trump can seize the opportunity to prove himself in snooker's most distinguished competition.
"We've lost O'Sullivan now and Judd is ready to become the people's champion," said Doherty.
"He's flamboyant and quick and people love to watch him play - I love to watch him play.
"If he commits himself to the game then he can carry on from the likes of O'Sullivan, Higgins and [seven-time champion] Stephen Hendry."
Doherty added: "But what I would say to him is don't take your eye off the ball. You've achieved number one, but you haven't achieved greatness just yet, although it's there for the taking.
"Now is the time to keep the hard work going and stay there and accumulate title after title, because that's what Hendry did."
