Mindful Golf
This article talks about how to apply mindfulness to your golf game. It discusses the two brain processing symptoms (fast and slow thinking) and how to use both to improve your mental game of golf.
Dealing with slow play
Every time you are faced with adversity on the golf course, whether it's slow play, or bad weather, or an opponent who just can't seem to miss, it's an opportunity to work on your mental game. Focus on the things you can control, and be methodical about it. With time, this will become your natural response, and lead to improved performance.
