The "3 Keys" principle is also found in sports psychology. What are the 3 things I need to do to be successful at x task? Whether its kicking the game winning field goal, making the free throw in the basketball game, or running a slalom pass. And when thinking about these three things, always think in the positive, not negative. For example, think "start wide" vs "don't start narrow". When mentally preparing for something, your body somehow always ignores the "don't" part of a negative statement, causing you to often do exactly what you're trying to avoid doing!
