Daniel, a 36-year-old tennis player, had the skill to beat almost anyone at his club—at least in practice. But tournaments told a different story. When the stakes were high, Daniel’s game fell apart. Nerves set in. Distracting thoughts crowded his mind. A single poor shot could send him spiraling into frustration. He would lose matches he knew he should have won—sometimes to players with far less skill. Over the years, Daniel worked with multiple tennis pros and tried everything: visualization, goal setting, positive self-talk, relaxation techniques. These helped a little, but never enough to break the pattern.
