The Magic of Thinking Big by David J. Schwartz is one of the most enduring self-help books ever written, first published in 1959 and still widely read more than six decades later. Schwartz, a professor at Georgia State University who spent years studying successful people, distills his observations into a practical philosophy: the size of your thinking determines the size of your results. The book's central premise is that belief is the most powerful force available to any human being, and that by deliberately cultivating bigger, bolder beliefs, anyone can achieve dramatically better outcomes in every area of life.
Schwartz begins by addressing what he calls excusitis, the disease of making excuses. He identifies four common varieties: health excusitis, intelligence excusitis, age excusitis, and luck excusitis. For each, he provides concrete evidence showing that these excuses are unfounded. People with serious health challenges have built empires, people of average intelligence have outperformed geniuses, people at every age have launched successful ventures, and luck is simply the residue of preparation meeting opportunity. The cure for excusitis is to stop making excuses and start making progress.
The book then moves to the mechanics of belief. Schwartz argues that belief works like a thermostat for achievement. When you believe you can accomplish something, your mind begins working on ways to make it happen. When you believe you cannot, your mind shuts down the creative process entirely. He introduces the concept of thinking big as a deliberate mental discipline, not a feel-good platitude. Thinking big means setting higher standards, refusing to accept mediocrity, and visualizing yourself in the role you want rather than the role you currently occupy.
One of the book's most practical chapters deals with the fear of failure and the fear of what others think. Schwartz provides a systematic approach to conquering fear through action. He argues that confidence is not something you either have or do not have; it is something you build by doing the thing you are afraid to do. He recommends a deposit of positive thoughts and experiences into your mental bank to draw upon when doubt arises. Each small victory becomes evidence that supports a bigger self-image.
Schwartz devotes significant attention to the power of environment on thinking. He notes that the people you surround yourself with have an enormous influence on the size of your ambitions. If you spend time with small thinkers, you will think small. If you surround yourself with people who think big and take action, your own thinking will expand accordingly. He advises readers to seek out first-class environments in every area of life, from the books they read to the clubs they join to the conversations they have.
The book also addresses how to think and dream creatively. Schwartz distinguishes between traditional thinking, which asks whether something can be done, and creative thinking, which asks how it can be done. He provides exercises for stimulating creative thought, including the practice of asking yourself how you can do more, how you can do it better, and how you can find opportunities where others see only obstacles. He argues that the most successful people are not necessarily the most talented but are the most creative in applying their abilities.
Schwartz explores the psychology of leadership and influence. He argues that people naturally follow those who demonstrate confidence, vision, and genuine concern for others. He provides practical techniques for winning cooperation and building loyalty, including the principle of putting service first, treating every person as important, and practicing the habit of thinking about others' interests before your own.
Another key theme is the importance of setting goals and creating concrete plans. Schwartz argues that vague desires produce vague results, while specific, written goals with deadlines produce specific outcomes. He recommends a thirty-day self-improvement program in which readers commit to definite actions that move them toward their goals. He also discusses the importance of investing in yourself through continuous learning and skill development.
Schwartz closes by addressing the habit of turning setbacks into stepping stones. He observes that every successful person has experienced failure, often multiple times. The difference between those who succeed and those who do not is not the absence of failure but the response to it. Those who think big view setbacks as temporary detours, learn from them, and keep moving forward. Those who think small view setbacks as permanent roadblocks and give up.
The Magic of Thinking Big remains relevant because its core insight is timeless: your external world is largely a reflection of your internal world. By deliberately raising the quality of your thinking, you raise the quality of your life. Schwartz's practical exercises and vivid examples make this book not just an inspirational read but a genuine manual for personal transformation.
Schwartz identifies the habit of making excuses as the number one enemy of success. He categorizes excuses into four types—health, intelligence, age, and luck—and shows how each one is a self-imposed limitation that keeps people trapped in mediocrity.
The thinking that guides your intelligence is much more important than how much intelligence you have.
Belief functions as a mental thermostat that regulates what you can achieve. When you genuinely believe something is possible, your mind activates its creative problem-solving abilities. When you doubt, those same abilities shut down. Success starts with believing you can succeed.
Believe it can be done. When you believe something can be done, your mind will find the ways to do it. Believing a solution paves the way to solution.
Schwartz argues that successful people are not necessarily more talented or intelligent—they simply think on a larger scale. By refusing to accept mediocrity and consistently setting higher standards, anyone can dramatically expand what they accomplish in life.
Think Big and you'll live big. You'll live big in happiness. You'll live big in accomplishment. Big in income. Big in friends. Big in respect.
Your environment—the people, conversations, media, and settings you expose yourself to—profoundly shapes your thinking. Schwartz urges readers to consciously engineer their surroundings to support bigger thinking and higher aspirations rather than allowing a toxic environment to shrink their ambitions.
People who tell you it cannot be done almost always are unsuccessful people, are strictly average or mediocre at best in terms of accomplishment.
Every successful person has a history of setbacks. The distinguishing quality is not avoiding failure but responding to it with resilience and learning. Schwartz teaches that defeats are only permanent when you accept them as such, and that every setback carries within it the seed of a comeback.
It is well to respect the leader. Learn from him. Observe him. Study him. But don't worship him. Believe you can surpass. Believe you can go beyond. Those who harbor the second-best attitude are invariably second-best doers.
Believe it can be done. When you believe something can be done, really believe, your mind will find the ways to do it.
