Why are some professionals able to influence complex environments and others not? What mindset and skills set them apart? The secret is called 'Executive Presence', a set of skills that differentiate those who are able to inspire deep respect, trust, and influence in highly demanding professional contexts.   This essential leadership concept was popularized in 2014 with the book Executive Presence by Sylvia Ann Hewlett. This work brilliantly defines it as "the ability to project credibility, composure, and influence to mobilize teams and make complex decisions, regardless of hierarchical level."
