Ko thinking ahead

F1 British Grand Prix – Valtteri Bottas pole position lap

The world number one appears to have maturity beyond her years; she's well aware that her golf career won't go on forever, and she already has an eye on when it could finish and what she'll do when it does. 

Thirty is the number in Ko's mind, and next month she will begin an online psychology course to prepare herself for future endeavours.

"I say my plan is to retire when I'm 30 so I'm not just going to go to the beach and hang out for the rest of my life," she explained.

"There's always a second career that comes along with it and I'm trying to build up towards it and, because I'm playing a sport, psychology links well with it.

"You just never know what's going to happen."

Ko will begin this week's Australian Open with a new caddy on her bag, with Jason Hamilton, who previously worked Yani Tseng, taking over the duties.

The Korean-born Ko auditioned eight caddies during her first season on tour before deciding to team up with Hamilton. It is Hamilton's sense of humour as much as his golfing knowledge which Ko has been drawn to.

"Personality-wise I like Jason, how he makes dumb jokes when I make a silly mistake because it makes me get over what happened," she explained.

"Bad jokes is part of my criteria."
