The Magic of Thinking Big

The summary

What you believe about your own capacity sets the ceiling on everything you’ll attempt, and attempts are the only thing that ever produces results. That’s the whole engine of David Schwartz’s book. Belief comes first and generates the skill and energy to follow through, not the other way around. “When you believe something can be done, really believe, your mind will find the ways to do it.” People who expect to succeed reach their goals far more often than the equally capable people who doubt themselves, partly because conviction makes others believe in you too. The size of your success tends to match the size of your belief. The trouble is that most people quietly talk themselves out of a bigger life, and they do it in a few predictable ways.

Excusitis and the fears that shrink you

Schwartz names the first mechanism “excusitis,” the disease of explaining away your failures. It comes in familiar strains: health (“I’m not well enough”), intelligence (“I’m not smart enough”), age (“I’m too old, or too young”), and luck (“things never go my way”). The cure is to fix your attention on your assets instead of your limitations and to refuse to argue yourself out of an opportunity. Fear works the same way, and the antidote is the same: isolate the specific fear, then act on it. Afraid of failing a test? Spend the worrying time studying. Afraid of losing a customer? Give better service. Afraid of people? Remember they’re more alike than different. Action starves fear; inaction feeds it. It helps to manage what you keep in your “mind bank”—deposit your achievements and compliments, refuse to withdraw old failures—and to behave confidently until you feel it, which can be as concrete as sitting up front, walking briskly, holding eye contact, speaking up in meetings, and smiling big.

Big thinkers paint big pictures

Schwartz contrasts two neighbors: one sees himself as a poor man fated to a run-down apartment forever, the other treats his current struggle as temporary and pictures himself an executive in a comfortable suburban home. The second man will go further, because big thinkers specialize in building positive, forward-looking pictures in their own minds and other people’s, and they use language that produces those pictures. Just as corrosive as excuses are the petty preoccupations that swallow attention—stewing over a small slip in a speech instead of the message you came to deliver, or winning a trivial argument at the cost of peace. Keep asking “is this really important?” and let the small stuff go. This bleeds directly into creativity, which Schwartz frames not as a gift reserved for geniuses but as finding better ways to do ordinary things. It starts with believing a solution exists, because disbelief shuts the mind down. Ban “it can’t be done,” ask yourself “how can I do this better?” and “how can I do more?”, and listen more than you talk, since ideas arrive faster when you’re taking in other people’s.

You are what you think you are

Your self-image quietly dictates how you act, and how you act shapes how others treat you. Think of yourself as inferior and you’ll behave that way and be taken at your word. So Schwartz has you manage the inputs. Upgrade your appearance and you feel more capable and read as more important. Treat your job as genuinely vital and your mind starts feeding you ways to do it better. Give yourself honest pep talks, and periodically ask “is this how an important person would think?” Environment matters just as much: the people around you either lift your ambition or smother it, so seek out big thinkers, avoid chronic negativity, and stay out of gossip, which he calls poison.

Action is the only thing that counts

Ideas are worthless until you move on them, and the people who wait for perfect conditions wait forever. Take action now and handle obstacles as they show up; the acting itself builds the confidence you were waiting to feel. Be the kind of person who volunteers rather than waits to be told. When something goes wrong, skip the blame—study the setback, find your own part in it, and adjust. Give the whole thing direction by setting ambitious ten-year goals across work, home, and social life, then breaking them into monthly and daily steps so every small task becomes a move toward the big one. The same outlook makes you a better leader: think from other people’s point of view, hold high standards others will rise to, and when you must criticize, do it privately—open with praise, name the one thing to fix, and close with praise again. Lyndon Johnson, Schwartz notes, made a point of learning everyone’s name and praising their work.

The bottom line

Belief is the engine; action is the vehicle. Nearly everyone underestimates what they could attempt, and the gap between them and the people who achieve more is mostly excuses, small thinking, and waiting. Read this if you’re ready to stop hedging and start acting on a bigger version of your ambitions.
