Fresh off a top-25 finish on home soil in February, Khan is determined to improve on his form and get another good result at Indonesia's premier golf tournament.
There's no reason why I cannot get another good result in Jakarta. It's all about self-belief and whether you can do it.
"Nothing is impossible and you just got to tell yourself you can do it," said Khan.
Khan finished ninth at the CIMB Niaga Indonesian Masters last year and will face another stern test with the likes of former world number one Lee Westwood of England, Korea's Y.E. Yang and Denmark's Thomas Bjorn expected to draw the crowds to the Royale Jakarta Golf Club later this month.
"Winning tournaments on the Asian Tour is always special and those two wins have given me lots of confidence.
"I've improved a lot since then and as long as I believe in myself, I'll do well," said Khan.
The Indian has grown in maturity and stature since he first made his attempt at earning his Tour card on the region's premier Tour through Qualifying School.
With limited playing opportunities, Khan was again left to rue another missed opportunity when he lost in a play-off on home soil in 2013.
But the Indian finally found success with his two victories at home and in Chiangmai last year and will be seeking a third at the CIMB Niaga Indonesian Masters.
"I don't give up. Even when I don't win, I try harder again and that is my secret to success," said Khan.
