I tell this story to illustrate the truth of the statement I heard long ago in the Army: Plans are worthless, but planning is everything.
Dwight David Eisenhower (1890-1969) American general, US President (1953-61)
Speech, National Defense Executive Reserve Conference (14 Nov 1957)
Quoted in R. Nixon, Six Crises, "Krushchev" (1962) as "In preparing for battle I have always found that plans are useless, but planning is indispensable." Sometimes paraphrased as "Plans are nothing; planning is everything."
