( CNN ) -- Rory McIlroy has apologized for his decision to walk off the course at last week 's PGA Tour tournament , and insists he will not repeat the mistake anytime soon . The world No . 1 left fellow professionals , fans and commentators in shock after leaving in the middle of his second round at the Honda Classic in Florida , where he was defending his title . The Northern Irishman had two bogeys , a double bogey and a triple bogey before hitting his tee shot at the 18th into the water , having started at hole nine . That led him to walk away citing a sore wisdom tooth , although he now admits that his actions were wrong and regrettable . `` I realized pretty quickly that it was n't the right thing to do , '' McIlroy told reporters Wednesday . `` No matter how bad I was playing I should have stayed out there . `` I was n't in a good place with my golf game . My head was all over the place . It was a mistake . Everybody makes mistakes -- most of my mistakes are in the public eye . `` I 'm 23 . I 'm still learning . I have learned from it and it wo n't happen again . '' A year in sport is a long time and McIlroy 's start to 2013 pales into insignificance compared to the form he was showing 12 months ago . Following the signing of a 10-year deal with Nike , which is reported to be worth $ 250 million , McIlroy has failed to recapture the magic which secured him the 2011 U.S. Open and 2012 PGA Championship titles . Since changing from his Titleist clubs to the Nike brand , he has failed to shine , missing the cut at Abu Dhabi and exiting the WGC Accenture World Matchplay event in Arizona at the first-round stage . With the Masters in Augusta on the horizon , McIlroy is aiming to rekindle the form which propelled him to the top of the PGA and European Tour money lists last year . And he is now hoping to start his resurgence at the $ 8.75 million WGC Cadillac Championship at Doral Thursday -- beginning with his swing . `` I know it 's purely the swing . The equipment is fantastic . No problem at all , '' he said of his new equipment . `` When I make a good swing it does exactly what I want . It does n't make a difference what clubs I play . `` I 'm trying to change my swing but I 'm trying to change it back to where it was . I have been in that position before and I can get it back again . `` There 's no quick fix in golf . You 've got to get to the root of the problem . It 's still a work in progress . '' McIlroy also revealed that he is waiting before deciding whether to add an extra event to his schedule before the Masters begins on April 11 . His only other scheduled tournament after Doral is the Houston Open from March 28-31 . `` I was waiting to see how I do this week , '' he said . `` Right now I have n't made a decision . The likelihood is I wo n't add an event . It 's a possibility . I do n't think it 's likely . ''
