Who really said it
The Difficult We Do Immediately. The Impossible Takes a Little Longer
Calonne is where the trail starts, but not where this sentence comes from. The earliest record, printed in 1794, has him telling Marie Antoinette: “If it is possible, madam, the affair is done; if it is impossible, it shall be done!” The version in circulation today — difficult/immediately, impossible/a little longer — is an American military slogan documented in 1942, after a century and a half of the saying being reworded and re-credited to a long line of other people.
