Clarke, currently ranked 52nd in the world, has not won an individual tournament since the 2003 WGC-NEC Invitational.
'I have just got to keep on playing and doing what I am doing,' Clarke said ahead of the Singapore Masters, which begins Thursday. 'I have not been known for my patience in the past, I have tried to force things a little too much. But at the minute I am having to be patient.'
Among the top players who've made swing changes after barren spells include World No. 1 Tiger Woods, a close friend of Clarke's.
The Northern Ireland golfer has also been spending more time with his children following the death of his wife, Heather, who died of breast cancer at the age of 39 in August last year.
Clarke is in Singapore for the first time, and is joined by Ryder Cup teammates David Howell and Lee Westwood of England. Outgoing Ryder Cup captain Woosnam is also at the US$1.1 million tournament, played at the Laguna Golf and Country Club.
The GOLF CHANNEL will have exclusive coverage of all four rounds beginning at 9:30 a.m. ET Thursday.
