Positive change rarely comes by accident. It’s the byproduct of hard work and sacrifice by large groups of people, driven by truly ambitious leaders. However, rarely are these leaders subject matter experts in every aspect of their endeavor.
Mark Zuckerberg had no experience running operations, but Sheryl Sandberg, Facebook's COO did.
Elon Musk had no experience in Space Exploration, but SpaceX's President and COO Gwynne Shotwell did.
Examples of visionaries filtering their ambition through experience are present across every truly impactful organization. From presidencies to leading companies.
There are also many examples when ambition wasn't filtered, for example in this pandemic you have world leaders pushing un-proven ideas.
Keep in mind there is a difference between filtration and dilution. Dilution is often the case in stagnant or declining organizations.
Great leaders are able to consistently filter their ambition through the experience of their team, driving impactful change. Bad leaders consistently do the opposite.
