The hardest shot in golf is always the next one. While lessons help us improve, the real key to getting better lies in the mind. Our mindset is the most powerful tool we have to improve every part of our game. We need to believe that what we’re learning is truly working. This explains why we excel on the range—because we convince ourselves by seeing good shots. On the course, we measure success through our score, and that’s where our belief in our ability needs to be strongest.
