'The game of golf is 90 percent mental and 10 percent physical."
This quote from Jack Nicklaus has been used many times to help describe how tough the game of golf really is.
An example would be the tale of Grayson Murray who won the 2017 Barbasol Championship, but just a few years later at the same tournament he walked off the course.
Murray, who started his first round on the 10th hole made the turn at five-under par, just three shots off the lead.
But the 28-year-old's tee shot on the first went out of bounds and he re-teed on route to a double-bogey six.
After three straight pars, he bogeyed No.5 and then followed that with another double bogey.
Still at even par through 15 holes, Murray's tee shot on the par-four seventh sliced onto the eighth hole's fairway, whereupon he then decided to call it a day.
Last July, Murray stepped away from the sport to treat mental health issues and according to Dr Bhrett McCabe, a sports psychologist who works with several PGA Tour players, it's very important to know which of the five personality types every golfer would come under.
The "Over Enthusiastic" personality type of golfers play their best golf when they get excited and show a lot of emotion.
"The Tactician" gets very tactical and detailed, while the "Bubble Player" is the classic, get-in-the-zone, game-face player.
"The Worrier" is the player who needs to worry in order to play their best.
McCabe explains that when the pressure ticks up, some players need to resolve their worries by worrying about worrying and complaining about things out of their control.
Finally, the "Chosen Player" accepts things are out of their control and submits to it.
They release themselves to the will of fate or some other higher power.
