Rory McIlroy says his Hong Kong Open triumph shows he can now grind out victories, a vital quality if he is to reach number one in the world.
After shooting an opening 64, McIlroy dropped three off the pace after three rounds in Hong Kong but a closing 65 saw him triumphing by two shots.
"On Friday and Saturday, I really did struggle," said the world number two.
"To be able to win when you're not playing your best is what the likes of Tiger did week in and week out."
McIlroy's win keeps alive his hopes of pipping Luke Donald to The Race to Dubai title.
The Northern Irishman will secure the order of merit title if he wins in Dubai and Donald finishes outside the top nine.
McIlroy added:"I sort of experienced the same thing in the Shanghai Masters this year, having to really fight for it," he said.
"I was one behind with four holes to go, drew level on 18 and won in the play-off.
"That's something you're going to have to do if you want to be a great player."
On Sunday, McIlroy drew level by the turn in Hong Kong before a holed bunker shot at the 18th helped him complete a two-shot win over Gregory Havret.
"It would be nice to walk up the last with a four-shot lead every time but that's just not going to happen. It was nice to finish it off like this."
McIlroy's recent itinerary has taken in the Korean Open, the China Golf Challenge that saw him play seven courses in seven days, the Grand Slam of Golf in Bermuda, the Shanghai Masters, the World Cup on Hainan Island and then Hong Kong.
After switching management companies and admitting the travelling had taken its toll, McIlroy insisted next year would see him scale back his commitments.
"You definitely won't see me go on a stretch like I have done this year but that's nothing to do with my previous management company.
"That was me just wanting to play, just saying 'you know what, last part of the year I'm going to go and I'm going to play', that's what I wanted to do," he said
"There's no one really to blame but myself in that regard and yeah, I'd love to come back to Hong Kong.
"This is one of my favourite tournaments of the year and I'll do all that I can to come back."
