Grit by Angela Duckworth: A Review

Note: This is an analysis based on public sources — the book's official description, published reviews, and reader feedback. I have not read Grit personally. I am writing about what the book promises and what public sources say about it, so you can decide whether it is worth your time.

If you have ever been told you are "not a genius" — or if you have told yourself that — this book was written for you. Angela Duckworth's central claim is uncomfortable and liberating at once: the secret to outstanding achievement is not talent. It is a blend of passion and perseverance she calls "grit."

What the book promises

Duckworth, a psychologist at the University of Pennsylvania and a 2013 MacArthur Fellow, argues that talent matters less than most people think. What matters more, she says, is a combination of passion (a enduring interest in a long-term goal) and perseverance (the ability to keep going despite obstacles, failure, and monotony) [citation:1][citation:3].

The book draws on her own story — the daughter of a scientist who often pointed out her lack of "genius" — and on fieldwork with West Point cadets, teachers in tough schools, and National Spelling Bee finalists. She also interviews high achievers, from J.P. Morgan CEO Jamie Dimon to New Yorker cartoon editor Bob Mankoff to Seattle Seahawks coach Pete Carroll [citation:1].

Among the key ideas the book explores: why effort counts twice toward a goal, how grit can be learned regardless of IQ, how lifelong interest is triggered, and the "Hard Thing Rule" for families [citation:1].

What public sources find useful

The book's core argument resonates with readers who have seen sustained effort pay off in their own lives. One reviewer on Amazon.com.br describes it as "an excellent starting point for setting goals and executing them, for discovering your purpose and staying focused on it" [citation:4]. The writing is widely described as accessible and engaging — Duckworth translates academic research into plain language through real stories [citation:9].

A Library Journal review notes that Duckworth's personal history (growing up hearing "you're no genius") gives the book an unusual credibility: she is not arguing from a position of natural advantage, but from someone who had to build grit herself [citation:2].

What public sources find limited

The most common criticism is structural. A widely shared reader review on Amazon.com.br argues that the book ignores socioeconomic conditions: "It talks about grit and talent and says nothing about equal opportunities. Can someone who was born near sugarcane fields and works 12 to 15 hours a day really succeed with all the grit in the world? Can they buy an instrument?" [citation:4]. The reviewer calls the book "the intellectual autobiography of its author" and says the examples are exceptions from first-world contexts [citation:4].

A critique on LinkedIn makes a related point: grit is presented as a primary driver of success, but "structural advantages, timing, access and sheer randomness receive far less attention." The concern is not with perseverance itself, but with how narrowly the concept is framed [citation:13].

Other readers note repetition. A community comment on a library catalog says the book is "decent" but "at times a bit redundant," and that the last third is about parenting — which some readers without children skipped entirely [citation:2]. The Amazon.com.br reviewer also calls it "more of the same: success stories dressed up as scientific narrative" [citation:4].

Who it may suit

• People who want a research-backed case for effort over innate talent.
• Readers who appreciate accessible psychology with real-world examples.
• Parents and educators looking for a framework to encourage persistence in others.
• Anyone who has felt dismissed as "not talented enough" and wants a counterargument.

Who it may not suit

• Readers who want a serious engagement with structural inequality and opportunity.
• People who dislike the self-help tone or repetitive success stories.
• Anyone looking for a clinical or theological treatment of perseverance.
• Readers who already know the basics of the "grit" thesis and want something more nuanced.

My opinion (labeled as opinion)

Based on public sources, Grit is a useful starting point, not a complete answer. The core insight — that effort compounds and that talent alone is not destiny — is worth taking seriously. But the criticism that the book underweights structural barriers is fair. Perseverance matters. So do opportunity, timing, and luck.

The book seems most valuable for readers who need permission to keep going on something they care about, and least valuable for readers who are looking for a structural analysis of why some people succeed and others do not.

Would I recommend it? Based on what public sources say: yes — with a condition. Read it for the case it makes about effort, not as a full explanation of success. If you want a book that takes inequality seriously, this is not that book. If you want a book that argues persuasively that what you do with what you have matters, this may be worth your time.

But consider this before you close this page: the book costs less than a dinner, and the question it raises — what actually drives achievement — is one most of us have asked ourselves. The risk of reading it is low. The risk of never examining your own assumptions about talent and effort is the same as always.
