It didn't help that next to me kids as young as 7, who Ko had been teaching, were cracking balls with pinpoint accuracy hundreds of metres down the fairway.
Or that the club I was using, I was told, was part of a kit worth twice as much as my car.
Head still. Don't try hit it too hard. It's all in the hips, right?
My shots were a bit wonky but not too bad and I managed to avoid hitting anyone.
Ko, a patient and encouraging tutor, said my weight was a little too far back and I should focus on shifting it forward. She also said my arms were too stiff and straight.
"Your down-swing is pretty good so keep your arms loose. I think you've got potential - everyone's got potential."
Today, Ko takes part in a charity event at the Takapuna Golf Course in which participants pay to play with or against Ko on the 10th hole.
