One of my Intel colleagues, a Harvard MBA told me a story of HBS students eager to take John Kotter‘s leadership class, at the time called “Power & Influence.” The students thought that Kotter’s course would teach them how to become calculating and ruthless. He amusingly remembered that Kotter’s course taught them the exact opposite: managers must first learn to be humble, connect and gain the respect of their colleagues and subordinates, before attempting to lead, or they would be doomed. Kotter’s book of the same name is filled with case studies of “ruthless” people who failed and those with humility who succeeded.
