"0 Kalki 00:04, 5 January 2007 (UTC) I would normally rank this a 3, if I were confident of it's authorship, but though this has been attributed to Coolidge, I have found no definitive source; though in one book I actually found the definite statement that he said this on the 4th of July 1872, this would be quite extraordinary, as that was the day he was born. Some attributions state that entrepreneur Ray Kroc used it as an "inspirational dictum" but not clearly stating any author, and thus I am doubtful of attributing it to Coolidge, and reluctant to use it until authorship is more clearly determined."
