One of my favorite stories is when I was playing with my old High School in a practice round. My brother was the golf coach so I got to play and get a chance to help out a little. There best player was Arjun Atwal a transfer student from India.
We were playing at Bethpage and were tied on last hole until "dum-dum" tried to force a 20 foot downhill birdie putt in the jar and three putted to lose by one stroke

Since then this guy who practiced relentlessly turned himself into a tour pro while I slid backwards into oblivion

Of course he was 18 and I was about 30 at the time.
Well yesterday he got his biggest win on US soil and will be back playing on PGA Tour next year

And I will be back outside the ropes giving him the needle when the tour comes back to NY over the summer
