Don't underestimate the emotional and positional power a CEO has
The emotional and positional power a CEO exercises is drastically underestimated by new CEOs. Serious attention to words and potential meanings, physical interactions and worst possible presumptions on body language and purpose, and methodology and chronology of decision-making and considerable resulting assumptions need to be managed.
Otherwise, a new CEO is in line to improperly use his power thinking many interactions are mutually agreeable, when, in fact, agreement is flowing from his organizational authority.
I report directly to my CEO, and he has directly related this advice to me.
