“The American Management Association reported on a study of managers who had been divided into two groups, those whose careers has flattened out and those whose careers were moving upward and onward at a rapid rate. They interviewed both groups to try to determine the differences that accounted for their relative levels of success and failure.
What they finally concluded was that it was not education, experience, background, networking or intelligence. The critical difference between success and failure was contained in the habit of taking the initiative. Managers and executives who were on the fast track were constantly moving out of their comfort zone and taking the initiative to try new things in new areas.
On the other hand, managers who were being continually passed over for promotion were continually waiting for someone to come along and tell them what to do. Once they had been given clear instructions, they seemed to be quite competent at carrying out their responsibilities. But the idea of initiating in the first place was alien to them.”
