When my students are encountering challenges in their golf game or during the practice time the first thing I tell them to do is to STOP doing what they are doing. In most cases, they are overcomplicating things, so they need to clear out the junk that is playing in their mind and just relax.
Once the mind is clear, THINK about where the ball could land. Visualize the shot and ANTICIPATE the potential outcomes. Swing and then RESPOND to the resulting outcome. It is important to focus on one shot at a time.
Golf is a mental game. The only way to persevere is to stay calm, relax and speak positively to yourself. There is always something to learn and achieve no matter how bleak you think it looks.
The stories below are great examples.
