The advice that sticks out I got from John Door, who in 2001 said, “My advice to you is to have a coach.”
My argument was, How could a coach advise me if I’m the best person in the world at this? But that’s not what a coach does. The coach doesn’t have to play the sport as well as you do. They have to watch you and get you to your best.
