Peak performance in any profession requires a combination of both the skills required to complete the task and the confidence needed to perform under pressure. Both are necessary: confidence without competence is useless, whereas competence without confidence is a waste. In The Confident Mind, you’ll learn strategies for ensuring that your own hard-won competence isn’t squandered due to a lack of mental fortitude.
Over the course of the book, you'll learn strategies for building confidence, dealing with adversity, fear, and setbacks, and adopting the appropriate mental filters to maintain a positive and constructive mindset. The strategies discussed in the book are all ultimately based on the concept of the self-fulfilling prophecy, or the idea that one’s thoughts regarding their own abilities in part determine those very abilities. Zinsser’s suggestions, therefore, primarily aim to set up positive self-fulfilling prophecies that boost confidence and performance (e.g., compiling a list of your top 10 past performances, reframing failure as an opportunity for growth, envisioning success, etc.).
The ideas are for the most part useful, but the book is not immune to criticism, particularly in regard to the idea of the self-fulfilling prophecy itself. Recent research has called into question the reach and power of the phenomenon, as some of the classic studies are not replicable or are riddled with methodological problems. Zinsser does not discuss this, and would rather have the reader believe that the phenomenon is indisputable.
In Zinsser’s defense, most of the questionable research on self-fulfilling prophecies concern “other-imposed” prophecies (your thoughts about other people affect their performance), rather than “self-imposed” prophecies (your thoughts about yourself affect your own performances), but it would have been nice for Zinsser to spell out the distinction himself.
Additional problems include the dialogues with his students, which seem contrived. His students never push back with any valid points and are painted as rather unreflective individuals. The purpose of these “dialogues” is simply to prove Zinsser’s points, and it shows.
Finally, Zinsser in general seems to prefer anecdotal evidence over objective science, and he fails to consider any counter-examples. For example, have his strategies ever failed to work for any of his clients? Are there examples of successful performers who use alternative strategies? Could a more intense focus on correcting mistakes—and not on constantly repeated self-affirmations—be a more effective approach, at least for some people? The reader will have to wonder, because these questions are never really addressed.
For all the issues, however, Zinsser does seem to have a strong track record (one of his clients, the professional football player Eli Manning, won two Super Bowls despite not being considered an elite quarterback skill-wise). Additionally, his strategies are always constructive: rather than dwelling on failures, weaknesses, and impossible comparisons, you focus on the positive aspects of your performance while reframing negatives into constructive opportunities for growth. For these reasons, while the book is not perfect, you’re likely to pick up on at least a few strategies to boost your performances.
