Core Idea

The Magic of Thinking Big suggests that success comes less from intellect, talent, or luck and more from how broadly one thinks. By purposefully developing a 'big thinking' mindset, people can move past self-imposed limits, build confidence, and use that confidence to act decisively. The book argues that by letting go of excuses, picturing success, taking initiative, and being around positive people, anyone can find much greater personal and professional satisfaction than they currently believe possible.

Key Takeaways from The Magic of Thinking Big

Cure Yourself of Excusitis

Identify and conquer the common excuses that limit your potential.

Schwartz explains that 'excusitis' is a 'sickness' that stops people from reaching their goals. He breaks down the four most common forms: health, intelligence, age, and luck. He asks readers to look closely at their self-imposed limits, often showing them to be groundless fears rather than real problems. By recognizing and fighting these excuses, one can find much untapped potential. The main idea is to stop explaining away inaction and instead focus on what can be done, not what supposedly cannot.

“The fellow who is going places is careful to avoid excusitis.”

In the book: Schwartz provides numerous anecdotes of individuals who achieved great success despite facing significant health challenges, perceived intellectual limitations, advanced age, or initial bad luck. He cites examples of people who turned physical disabilities into motivators or those who started successful ventures later in life.

Try this: When faced with a challenge, consciously identify any immediate excuses that come to mind. Then, actively reframe the situation by asking, 'What can I do despite this perceived limitation?' For example, if you think you're 'too old,' research successful people who started later in life and draw inspiration from their stories.

Think Big, Achieve Big

The size of your success is directly proportional to the size of your thinking.

Schwartz says that most people unintentionally limit their achievements by thinking small. They aim for modest goals and get modest results. He states that the human mind is a 'thought factory,' and the quality and size of its output (ideas, plans, actions) depend on the 'raw materials' (thoughts) put into it. To achieve big things, one must first think big, imagining grand possibilities instead of settling for small improvements. This means expanding one's mental scope and believing in larger aspirations.

“Success is determined by the size of one's thinking.”

In the book: Schwartz illustrates this with a story of a salesman who consistently sold small orders until he was encouraged to 'think big' by a mentor. Upon changing his mental approach and expecting larger orders, his sales volume dramatically increased. He also refers to the power of belief in shaping outcomes.

Try this: For any goal you set, challenge yourself to double or triple its scope. Instead of aiming for a 10% increase, aim for 100%. Visualize the successful achievement of this larger goal and plan accordingly. Act as if success is inevitable, not just possible.

Develop the Power of Belief

Belief in success is the foundational ingredient for achieving it.

Schwartz stresses that belief is the 'master switch' to success. He argues that the mind naturally works to prove what you believe. If you believe you can succeed, your mind will look for solutions and chances; if you believe you will fail, it will find reasons and problems. This is not just wishful thinking but a strong psychological idea where conviction drives action. Real belief is not passive; it is an active, energizing force that makes you overcome challenges and keep going until your goal is met. Doubt, on the other hand, stops you.

“Believe it can be done. When you believe something, your mind finds ways to do it.”

In the book: He recounts an experiment where a 'sick' patient was given a placebo but told it was a powerful new drug, and their condition improved significantly due to their belief. Conversely, he cites instances where individuals with all the necessary skills failed because they lacked confidence.

Try this: Before starting any task, consciously affirm your belief in your ability to succeed. Write down your goals and the reasons you believe you *will* achieve them. When doubt creeps in, immediately challenge it with evidence of past successes or by visualizing the positive outcome.

Action Cures Fear

Overcome fear and build confidence by taking decisive action.

Schwartz strongly states that fear mostly comes from not acting and from imagination. He disagrees with the common advice to 'think your way out of fear,' saying that just thinking about fear makes it stronger. Instead, he suggests a direct approach: take action. Even small steps can start to lessen fear and build confidence. Each successful action, no matter how minor, gives positive reinforcement, showing the mind that the feared situation is manageable. This builds up, eventually replacing fear with confidence and ability.

“Action cures fear. Indecision, postponement, and inaction feed fear.”

In the book: Schwartz describes how public speaking fear can be overcome not by worrying about it, but by actually getting up and speaking. He also mentions how people who are afraid of flying often overcome it by simply taking the flight, realizing their fears were unfounded.

Try this: Identify one area where fear is holding you back. Break down the intimidating task into the smallest possible actionable step. Then, commit to taking that step immediately. Repeat this process, gradually increasing the size of your actions. Don't wait for confidence to appear; let action build it.

Go the Extra Mile

Achieve extraordinary results by consistently doing more than is expected.

This idea is about doing more than expected and going beyond the minimum. Schwartz argues that average people do just enough, while successful people always look for chances to add value and do extra. This habit builds a good reputation, creates trust, and often leads to new opportunities and promotions. It is a mindset of generosity and excellence that sets you apart and shows real commitment to your work and your clients or colleagues. The 'extra mile' is where real difference and big growth happen.

“Go the extra mile. The rewards for going the extra mile are astonishing.”

In the book: Schwartz gives the example of a salesperson who, instead of just making the required number of calls, spent extra time researching clients and offering personalized solutions, leading to significantly higher sales and client loyalty. He also mentions executives who consistently took on more responsibility than their job description demanded.

Try this: In your job or personal life, identify one area where you can consistently do more than is expected. For example, if you're asked to complete a report, add an extra analysis or present it in a more engaging way. Always look for ways to add value without being asked.

Think Like a Leader

Cultivate the qualities of leadership through thought and action, regardless of your formal title.

Schwartz states that leadership is not just about position or title; it is a way of thinking and acting. He lists several key leadership qualities anyone can develop: thinking about progress, asking for and giving useful criticism, and taking initiative. Leaders are proactive, solve problems, and inspire others. They do not wait for permission; they see what needs to be done and do it. By adopting a leadership mindset—taking responsibility, building positive relationships, and imagining solutions—people can influence others and earn respect, eventually moving into formal leadership roles.

“Think like a leader, and you will become a leader.”

In the book: He tells the story of a junior employee who, by consistently taking initiative and solving problems for his department, was eventually promoted over more senior colleagues who simply 'followed orders.' He also emphasizes the importance of 'selling' your ideas to others, a key leadership trait.

Try this: In your current role, identify a problem or inefficiency and propose a solution, even if it's outside your immediate responsibilities. Practice asking 'What can I do to improve this?' and 'How can I make things better?' regularly. Take responsibility for outcomes, good or bad.

Use Your Imagination to Generate Ideas

Unleash creative problem-solving by actively employing your imagination.

Schwartz promotes imagination as a key tool for success, not just a childish activity. He argues that successful people actively use their imagination to picture solutions, create new products, and foresee future problems. Instead of just accepting things, they imagine possibilities and mentally 'try out' different approaches. He distinguishes between 'daydreaming' (unproductive fantasy) and 'creative imagination' (purposeful mental construction). By purposefully using your imagination, you can innovate, overcome problems, and find new ways to reach your goals, turning abstract thoughts into real plans.

“Imagination is the laboratory of the mind.”

In the book: He cites inventors and entrepreneurs who first 'saw' their creations in their minds before bringing them to reality. He encourages readers to ask 'How can I do this better?' and 'How can I do more?' to stimulate imaginative thinking.

Try this: When faced with a challenge, dedicate time to brainstorming without judgment. Imagine multiple solutions, even seemingly impossible ones. Visualize the ideal outcome and then work backward to identify the steps. Regularly ask 'What if...?' to explore new possibilities.

Related ideas: creativity, innovation, problem-solving

Invest in Yourself

Continuously learn and grow to expand your capabilities and value.

Schwartz emphasizes that personal growth is an ongoing process and an important investment. He encourages readers to always be learning, looking for new knowledge, skills, and viewpoints. This includes reading widely, watching successful people, and self-critiquing. The more you learn and grow, the more valuable you become to your employer, your community, and yourself. This is not just about formal education; it is about having a strong curiosity and a commitment to self-improvement in all parts of life. Standing still stops big thinking.

“Invest in yourself. Knowledge is power, and it pays the best interest.”

In the book: He highlights how successful individuals often dedicate time daily to reading or learning new skills, even after achieving significant success. He encourages readers to make a habit of reading books that inspire and educate, rather than just for entertainment.

Try this: Dedicate at least 30 minutes each day to learning something new related to your goals or personal development. This could be reading a non-fiction book, listening to an educational podcast, or taking an online course. Actively seek out mentors or individuals who can teach you new perspectives.

Control Your Environment

Surround yourself with positive influences that uplift and inspire big thinking.

Schwartz makes a strong point about how much one's environment affects their thinking and success. He argues that you become like the people you spend the most time with, and that negative, small-minded people can subtly but strongly bring you down. On the other hand, being around positive, ambitious, and successful people can raise your aspirations and provide valuable support and inspiration. This does not mean leaving friends, but purposefully seeking out connections that support big thinking and positive action, and limiting time with those who create negativity and mediocrity.

“Guard your environment. Your environment makes you.”

In the book: He uses the analogy of 'social poison' – how associating with negative people can infect your own mindset. He contrasts this with individuals who actively sought out mentors and peers who were already successful, and how this drastically accelerated their own growth.

Try this: Evaluate the five people you spend the most time with. Do they uplift you, challenge you positively, and encourage your big dreams? If not, actively seek out new connections with people who embody the qualities you aspire to. Minimize time spent with consistently negative influences.

Practice Self-Leadership in All Areas

Apply big thinking principles consistently across your job, home, and social life.

Schwartz does not limit big thinking to career goals; he applies it to all parts of life: marriage, family, and community. He argues that the same ideas of positive belief, action, and overcoming excuses are just as important for building strong relationships and contributing to society. True success is complete. By leading in your personal life—planning, communicating well, taking initiative, and focusing on solutions—you can create harmony, find personal satisfaction, and inspire those around you. This combined approach ensures that big thinking is not just a professional tool, but a full philosophy for a successful life.

“Success in anything begins with self-leadership.”

In the book: He gives examples of how applying 'big thinking' to marital problems (e.g., focusing on solutions instead of blame) can strengthen relationships. He also discusses how community leaders apply these principles to solve civic challenges.

Try this: Identify one area of your personal life (e.g., family relationship, personal finance, health) where you want to see significant improvement. Apply the 'think big' mindset by envisioning the ideal outcome and then taking concrete, leadership-oriented steps to achieve it. Don't let small problems become big ones through inaction.
