Charles Marshall

American author, motivational speaker & comedian

Charles W. Marshall is an American motivational speaker, comedian and author who addresses corporate and civic audiences across the United States. His 2003 book Shattering the Glass Slipper contains the sentence most often cited as the source of this quotation — written in his own voice, with no reference to C.S. Lewis. Even so, his phrasing differs from the tidy popular version, and the underlying idea long predates him.
