I was about 15. Once I got out of high school and got into college, that was my main focus, to play professional golf. For me, it is long irons. Say a long bunker shot. From 40-70 yards is the hardest overall.
Most players try to avoid that at all cost.
But I have gotten good at it. We get to travel together, play practice rounds, help each other on the range since we know the swings well. It is nice to have family out there. We have a good time together. It is close to being the second best in the world.
