"I've learned that mistakes can often be as good a teacher as success"
About this Quote
A tough-minded leader like Jack Welch understood a paradox many overlook: the path to excellence runs straight through error. As longtime CEO of GE, he was famous for performance pressure, meritocracy, and relentless execution, yet he also built systems that made it safe and expected to surface mistakes, analyze them, and turn them into institutional learning. That balance is the core insight here. Success brings applause and inertia; it often hides sloppy processes behind a lucky outcome. Mistakes, by contrast, deliver sharp, unambiguous feedback. They expose causal chains that can be studied, improved, and scaled.
Not all errors are equal. Welch prized what some call intelligent failure: risks taken with a clear hypothesis, appropriate controls, and a willingness to learn quickly. Carelessness was not tolerated, but curiosity was rewarded. GE practices such as Work-Out sessions and a culture of candor encouraged people to name what went wrong without euphemism. Even Six Sigma, his hallmark of quality, is not a celebration of perfection so much as a disciplined obsession with understanding defects. The method assumes that a well-studied mistake is a map to a better system.
The practical implications are simple and demanding. Treat outcomes as data, not as identity. Run small, reversible experiments so that errors are affordable and instructive. Conduct post-mortems and ask the unflinching questions: What did we assume? Where did reality disagree? What will we change next time? Leaders must pair psychological safety with accountability, making it both acceptable to admit missteps and unacceptable to ignore their lessons.
The deeper lesson is about humility. Success teaches what worked once; failure teaches why things work at all. In volatile markets and careers, the advantage goes to those who metabolize mistakes quickly, converting them into better judgment, stronger systems, and the confidence that comes from having faced the truth and improved because of it.
