One thing is certain in business. You and everyone around you will make mistakes.

The line frames error as an unavoidable feature of commercial life rather than a personal failing. By stating that “you and everyone around you” will err, it normalizes mistakes across hierarchies and teams, discouraging blame and perfectionism. The implication is pragmatic: since missteps are certain, the competitive advantage lies in how quickly an organization notices, owns, and learns from them—building processes and a culture that treat failure as feedback. In a Branson-like entrepreneurial ethos, this supports experimentation, calculated risk-taking, and resilience, while also reminding leaders to design systems that anticipate human fallibility.
