“Nimitz ran a destroyer aground. He was then an ensign.”
People who never make mistakes never take chances. And, they never learn from their mistake. When McNamara was president Ford a subordinate made a $150k mistake. A reporter asked if he was going to fire the man and McNamara replied, “What, and give somebody else the benefit of a $150k education?”
I knew people in my career that were so afraid of making the wrong decision that they were incapable of making any decision. I had an old Master Sergeant who once told me “if you ain’t making mistakes you ain’t leading.”
What he meant was you gotta do something, some of your decisions will turn out wrong but if you got any smarts you will learn and most of your decisions will be correct.
