Hope is not a method and wishes are not plans

From Donald Sensing's Sense of Events.

When I was assigned to the Army Operations Center in the early 1990s at HQDA, the chief of staff was Gen. Carl Vuono. He sometimes found occasion during our briefings to him about current and planned operations to hammer home a point: "Hope is not a method and wishes are not plans."

Don't tell me what you hope will happen, don't tell me what you wish you could do, he repeated. "Give me a plan that makes it happen."
