Schwartz’s claim is disarmingly simple: your results grow to the size of your thinking.

The Magic of Thinking Big swaps IQ worship for beliefs that provoke resourcefulness, beginning by naming the epidemic “excusitis”—the convenient stories we tell about ourselves and others about age, talent or luck. His antidote is action: move first, and let courage catch up.

He teaches you to upgrade your self-talk, to reframe self-expectations positively, to visualise the best possible outcomes, and set larger, specific targets advanced by small, consistent steps. Schwartz shows how to curate yourself a better environment, too and go “first class” in effort. He also posits how to approach others: listen generously, give credit, present ideas with calm confidence—and treat setbacks as data.

If you feel stuck or feel you have a limited potential, this is a practical, behavioural toolkit for lifting your ceiling and getting more of the results you actually want.
