“The most effective (improvement) method of all: deliberate practice. It is the gold standard, the ideal to which anyone learning a skill should aspire.” – Anders Ericsson

Turn your practice sessions into deliberate practice sessions by adding S.P.I.C.E.:

Specific performance target

If you have vague performance targets like ‘get better’ or ‘succeed,’ you’re simply wasting your time. To improve performance, you need specific performance goals.

Steve Faloon was able to recite 82 digits by having clear goals the entire way. If he could successfully recite 39 digits, his sole focus was getting to 40 digits.

Book Summary: Peak - Secrets from the New Science of Expertise

“Deliberate practice involves well-defined, specific goals and often involves improving some aspect of the target performance; it is not aimed at some vague overall improvement.” – Anders Ericsson

Periods of intense undistracted focus

Before Steve attempted 39 digits, he gave himself an exciting pep talk (“You got this Steve!”) before concentrating intently on the numbers Anders gave him. For those 1 hour sessions all that mattered was hitting his targets.

“Deliberate practice is deliberate, that is, it requires a person’s full attention and conscious actions. You seldom improve much without giving the task your full attention. It isn’t enough to simply follow a teacher’s or coach’s directions.” – Anders Ericsson

Immediate feedback

To discover a mental representation that works, you’ll need to test various mental representations during each practice. In order to verify if a representation is effective or not, you’ll need to receive accurate and immediate feedback. The quicker the feedback, the faster you’ll improve your mental representation.

Steve knew if his approach was working after each attempt. Imagine if he had to wait 10 minutes before knowing whether the last six attempts were correct…

“Without feedback— either from yourself or from outside observers— you cannot figure out what you need to improve on or how close you are to achieving your goals.” – Anders Ericsson

Cycling between comfort and discomfort

Approach skill development the same way you’d approach bodybuilding: a period of discomfort (lift weights slightly heavier than what you can currently lift) followed by a period of ease and comfort (recovery phase) to grow new muscles and lift larger weights next week. Improvement only comes from a willingness to push yourself beyond your comfort zone followed by a willingness to fully rest and recover (expert performers sleep on average 8.5 hr / night).

“Deliberate practice takes place outside one’s comfort zone and requires a student to constantly try things that are just beyond his or her current abilities. Thus it demands near-maximal effort, which is generally not enjoyable.” – Anders Ericsson

Expert coaching from proven performers

Expert coaches provide effective mental representations to jump start your progress.

Expert coaching also heightens each aspect of the deliberate practice method by:

  • Ensuring you know the path to excellence and providing intermediate goals along the way.
  • Using social pressure to hold you accountable and raise the intensity of practice.
  • Providing accurate and immediate feedback because they know exactly what to look for.
  • Pushing you harder than you want, but not pushing you too far.

“Deliberate practice develops skills that other people have already figured out how to do and for which effective training techniques have been established. The practice regimen should be designed and overseen by a teacher or coach who is familiar with the abilities of expert performers and with how those abilities can best be developed.” – Anders Ericsson

The Ultimate Goal

“Deliberate practice both produces and depends on effective mental representations. Improving performance goes hand in hand with improving mental representations; as one’s performance improves, the representations become more detailed and effective, in turn making it possible to improve even more.” – Anders Ericsson

“Peak: Secrets from the New Science of Expertise” is an insightful and thought-provoking book by K. Anders Ericsson and Robert Pool that explores the science behind expertise and the path to mastery. The authors delve into the secrets of how individuals become experts in their respective fields, challenging conventional wisdom and shedding light on the remarkable potential of deliberate practice.

The book begins by debunking the myth of innate talent, arguing that it is not an inherent gift that separates experts from novices, but rather the result of focused and deliberate practice. Ericsson and Pool introduce the concept of “deliberate practice,” a form of learning characterized by a clear goal, feedback, and the commitment to continuous improvement. Through numerous real-world examples and studies, the authors illustrate how deliberate practice can be applied to virtually any skill or field, be it music, sports, or professional careers.

One of the standout aspects of “Peak” is its comprehensive exploration of the principles of deliberate practice. The authors outline how to structure practice sessions, set goals, and maintain motivation, emphasizing the importance of pushing one’s limits and seeking out challenging tasks. They also discuss the role of expert coaching in guiding individuals toward peak performance, highlighting the significance of regular, constructive feedback.

The book takes an in-depth look at various success stories, including the famous case of chess prodigy Bobby Fischer and the training regimen of accomplished musicians. These examples provide practical insights into the application of deliberate practice and the steps required to achieve true expertise. Ericsson and Pool also address the concept of “10,000 hours of practice,” popularized by Malcolm Gladwell, and clarify its nuances, explaining that it’s not just about accumulating hours but the quality of those hours that truly matters.

In the later chapters, “Peak” touches on how these principles can be applied in education, business, and everyday life, demonstrating that the quest for expertise is not limited to specific domains. The authors discuss the role of technology in enhancing practice and provide guidance on building a deliberate practice routine.

“Peak: Secrets from the New Science of Expertise” is a must-read for anyone interested in the science of skill acquisition and the journey toward mastery. Ericsson and Pool offer a well-researched and engaging exploration of the potential within each of us to become experts in our chosen fields. Their argument that talent is overrated and that deliberate practice is the key to achieving excellence is compelling and backed by a wealth of evidence.

The book is both accessible to the general reader and valuable for professionals looking to improve their performance. The real-world examples, coupled with practical advice on how to apply deliberate practice, make it a valuable resource for personal growth and development. Ericsson and Pool’s writing style is clear and engaging, making complex scientific concepts accessible to a wide audience.

In conclusion, “Peak” challenges conventional wisdom about talent and expertise, offering a roadmap for anyone looking to improve their skills and reach the pinnacle of their potential. This book is not just an academic exploration but a guide to practical self-improvement that can transform the way you approach learning and skill development.
