Gary Vaynerchuk pinpoints a specific childhood memory of impulsively buying a costly table at a card show and quickly turning a profit. This single event, which went against his peers' logic, cemented his self-belief and entrepreneurial drive for life.

This counterintuitive take implies that a flawless record may indicate a lack of risk-taking or unlearned lessons, while one blowup teaches invaluable, hard-won wisdom about risk management.
