I found this while random reading internet. Read Malcolm Gladwell's Outlier so I know it's the same concept as Beatles playing for 10'000 hours in Hamburg.
Quite inspiring, his dedication. And interesting experiment to test the concept.
Watched a few videos and his swing does not look pro, but apparently he is currently 3 HCP. Great job and considering he started golfing in 2010, I will say hell of a journey so far.
