Chapter 1 introduces the story of a Russian journalist named S who showed up at psychologist A.R. Luria's office in 1928 claiming to have an abnormally powerful memory. Luria studied S for 30 years and wrote a book about him, finding S's memory was virtually limitless. However, S was crippled by his inability to forget anything. His mind was constantly cluttered with trivial details and sensations.

While S's memory was seemingly sui generis, Foer suggests it may be possible for anyone to attain similar memorization abilities through training. He cites a study comparing the brains of mental athletes to a control group that found no neuroanatomical differences - only that the mental athletes were engaging different brain regions related to spatial memory and navigation. This suggests their skills were achieved through practice rather than innate ability.

The author gives examples of how different grit paragons conceptualize their beyond-the-self purpose:

• Jane Golden, founder of the Philadelphia Mural Arts Program, believes her purpose is beautifying the city and saving lives through public art. Despite chronic pain from lupus, she perseveres out of a "moral imperative" to serve others.
• Wine critic Antonio Galloni sees his mission as educating people to understand and enjoy wine, helping them appreciate its artistry and enrich their lives. Sharing his interest with others gives him a sense of purpose.
• As a teenager, the author herself found a sense of purpose in working with underprivileged kids through the Summerbridge educational non-profit.

Purpose looks different for different people, but the common theme is connecting personal passions and efforts to a cause or mission that transcends the self.

In the 1960s, childhood leukemia was a death sentence. Chemotherapy existed but inevitably failed as the cancer returned after apparent remission. Most doctors used chemo sparingly, thinking stronger doses would be too toxic for children.

Dr. Jay Freireich, an iconoclastic cancer researcher, tried the opposite approach. He used maximum dose chemo continuously rather than in one short burst. His regimen was brutal on children and caused immense suffering. But it worked - achieving the first-ever cures of childhood leukemia.

Freireich was uniquely suited to this approach because he had a horrific childhood himself - abandoned by his severely depressed mother at a young age, constantly hungry and in need. To him, imposing suffering to achieve a cure was a more tolerable trade-off than for researchers from more comfortable backgrounds.

Consider these examples of how even people with extraordinary memory abilities still forget and make mistakes, illustrating memory's imperfections:

• Akira Haraguchi, who memorized over 100,000 digits of pi, still forgot his wife's birthday.
• Legendary cellist Yo-Yo Ma once left his priceless cello in a New York City taxi.
• World memory champion Joshua Foer, who can memorize a deck of cards in under 2 minutes, admits these techniques don't make him immune to forgetting why he walked into a room.
• These anecdotes demonstrate that even the most exceptional memories aren't infallible or all-encompassing. Mistakes and lapses can happen to anyone - it's only human.

Joe Flom's rise to prominence as a lawyer exemplifies the complex interplay of cultural background, historical context, and individual effort in achieving success. His Jewish heritage, initially a barrier to entry in the WASP-dominated world of Wall Street law firms, ultimately became an advantage, leading him to specialize in the then-marginalized field of hostile takeovers. Born during a demographic trough, Flom benefited from a robust public education system and a favorable job market. Furthermore, his upbringing within a culture of meaningful work, shaped by the entrepreneurial spirit of the garment industry, instilled values of hard work, autonomy, and a direct link between effort and reward. These factors, combined with Flom's talent and ambition, positioned him perfectly to capitalize on the rise of mergers and acquisitions in the 1970s and 1980s, solidifying his status as a legal powerhouse. Flom's story underscores the significance of cultural legacies and opportune timing in shaping individual achievement and challenges the simplistic notion of success as solely a product of personal merit.

French chef Sébastien Bras achieved the culinary world's highest honor when his restaurant Le Suquet earned 3 Michelin stars.

In 2017, Bras did the unthinkable. He asked Michelin to remove Le Suquet from their guide, forfeiting his stars. He no longer wanted the anxiety of being judged or the pressure to conform to Michelin's narrow definition of culinary excellence. By stepping outside the mimetic system of haute cuisine, Bras rediscovered his thick desire - to create and share the terroir of his native Aubrac region through food, without fear of judgment.

Bras's story shows the courage it takes to renounce a mimetic game you've mastered. But the newfound creative freedom is worth it. As his story spread, other chefs were inspired to redefine success on their own terms.

The famous psychoanalyst Erik Erikson coined the term "identity crisis", but he himself went through one in his own twenties. Raised by his mother and step-father, he traveled Europe after high school, sleeping under bridges and taking art classes.

However, he wasn't just having an extended adolescence. By age 25 he was teaching art, studying education and psychoanalysis, meeting influential people in his field. By 30 he had a psychoanalytic degree and was launching his career as a teacher, analyst and theorist.

His identity capital came from productively using his twenties, not postponing adulthood indefinitely.

On its surface, the Polgár sisters' story reads like a typical child prodigy tale - three precociously gifted girls destined for greatness from birth. But a closer look reveals a different story - one of relentless hard work, strategic training, and a fanatically focused learning environment.

From the outset, the Polgár parents set out to mold their daughters into learning machines. They homeschooled the girls with an obsessive focus on chess, stripping away conventional subjects in favor of intensive drilling and practice.

But it wasn't just the volume of practice that set the Polgárs apart - it was the quality and design of their training. László, the mastermind father, instinctively grasped the principles of deliberate practice and ultralearning. He broke chess down into its component skills, and drilled each one to the point of automaticity. He immersed his daughters in the culture and lingo of grandmasters, so they would feel at home in the world they were entering.

Looking back, we can see the Polgár experiment as a blueprint for integrating ultralearning into education. By frontloading their training, specializing ruthlessly, and gamifying the learning process, the Polgár parents created an environment perfectly tuned for rapid skill acquisition.

Jim Jones, the mastermind behind the Peoples Temple, was a master manipulator who used his linguistic skills to attract and control followers from all walks of life. He employed code-switching techniques, seamlessly alternating between intellectual discourse and folksy charm to appeal to different audiences.

With African Americans, Jones highlighted his commitment to racial justice and peppered his speeches with Black church colloquialisms. When recruiting white hippies, he waxed poetic about socialist theory and quoted philosophers. Jones even coined loaded phrases like "revolutionary suicide" and "white night" to reframe disturbing concepts in a way that resonated with his followers. His ability to adapt his language to his listeners' backgrounds and desires was a key factor in his uncanny influence.

Srinivasa Ramanujan, one of history's most brilliant mathematicians, had an unconventional learning journey. Growing up poor in India, he had limited access to formal education or advanced math textbooks. One of the only resources he could get his hands on was a book by George Shoobridge Carr called "A Synopsis of Elementary Results in Pure and Applied Mathematics."

Lacking the solutions, Ramanujan was forced to derive the proofs himself. He spent countless hours not just reading the theorems, but reconstructing them from first principles. In cognitive science terms, he was engaging in an extreme form of retrieval practice - grappling with each concept until he could regenerate it from memory.

This intense retrieval practice honed Ramanujan's mathematical intuition to an extraordinary degree. Over time, he developed such a deep understanding of how numbers fit together that he began discovering new theorems the world had never seen. Despite his lack of formal training, he made breakthroughs that stunned the mathematical establishment.

Tennis great John McEnroe is a prime example of a fixed mindset athlete.

• McEnroe believed he should win because of his talent and got furious when he didn't. He blamed losses on everything but his own effort.
• His need to prove his superiority made him arrogant and combative with umpires, opponents, and even fans.
• After losses, McEnroe vowed he would redouble his efforts in training, but rarely did. He believed he should be able to win on talent alone.
• By contrast, rival Jimmy Connors had a growth mindset, relishing hard work and using failures to improve his game.

In studying the lives of successful people, Ray Dalio was struck by how Apple founder Steve Jobs embodied the qualities of a "shaper" - someone who can go from envisioning remarkable things to actually building them, often in the face of intense skepticism.

Reflecting on Jobs, Dalio notes: "Steve Jobs was probably the greatest and most iconic shaper of our time, as measured by the size and success of his shaping. Jobs built the world's largest and most successful company by revolutionizing computing, music, communications, animation, and photography with beautifully designed products."

But being a shaper is not all glamorous - it involves the taste for constant battle against skeptics and the ability to withstand failure. Dalio points out how a shaper like Jobs could never have achieved what he did without also developing.
