Some jobs require “nerves of steel.” Jobs that place you on the front lines of life and death—surgeons, fighter pilots, mountain rescue workers, firefighters, police officers, etc.—are not for the faint of heart. In fact, the calm bravery needed for such jobs sometimes made me a bit cynical of the term “managerial courage.” Courage to me was a word reserved for the very bold and very brave. It was not a word that pertained to office and boardroom work. But then I started our blog series on diversity—#4TechDiversity—and it has shown me how much managerial courage can do.
