“As a military officer, if I was in an operational command, I may know 50% or 60% of what is happening and the rest is kind of intuition. But based on what I know in my intuition, I have to make a decision. And if I wait for 100% certainty, the likelihood is that I’m going to be overrun or something; you have to act.” General Gordon Sullivan (Retired); Chief of Staff of the U.S. Army; 1991-95 ©
