Reflecting on Walmart's multi-year transformation, CEO Doug McMillan identifies the most common leadership pitfall: delaying actions you instinctively know are right. He advises leaders to trust their gut and move quickly, as organizations are often more capable of handling rapid change than perceived.

The best leaders act on incomplete information, understanding that 100% certainty is a myth that only exists in hindsight. The inability to decide amid ambiguity—choosing inaction—is a greater failure than making the wrong call.

Waiting for perfect data leads to paralysis. A core founder skill is making hard decisions with incomplete information. This 'founder gut' isn't innate; it's developed by studying the thought processes—not just the outcomes—of experienced entrepreneurs through masterminds, advisors, or podcasts.

As expertise develops, one can shift from rigid plans to relying on deep 'programming'—the sum of instincts and experience. This allows for adaptability in high-stakes situations, turning potential disasters into moments of authentic performance that a rehearsed script could never achieve.

While experience builds valuable pattern recognition, relying on old mental models in a rapidly changing environment can be a significant flaw. Wise leaders must balance their experience with the humility and curiosity to listen to younger team members who may have a more current and accurate understanding of the world.

A founder's retrospective analysis often reveals that delayed decisions were the correct ones, and the only regret is not acting sooner. Recognizing this pattern—that you rarely regret moving too fast—can serve as a powerful heuristic to trust your gut and accelerate decision-making, as inaction is often the biggest risk.

Intuition is not a mystical gut feeling but rapid pattern recognition based on experience. Since leaders cannot "watch game tape," they must build this mental library by systematically discussing failures and setbacks. This process of embedding learnings sharpens their ability to recognize patterns in future situations.

Contrary to the cultural narrative that aging diminishes relevance, experience brings profound advantages. Older leaders are often smarter, more in tune with their integrity, and less afraid to take risks or disappoint others, making them more effective and resilient.

Instead of a rigid framework, great decisions come from "terroir"—the right mix of ingredients. This includes deep customer empathy, market knowledge, and an intuitive grasp of constraints. This foundation allows a leader's gut instinct to function as a highly trained model.
