Eighty percent of success is showing up.

Woody Allen (b. 1935) American comedian, writer, director [b. Allan Steward Konigsberg]

Comment

Originally attributed to Allen by collaborator Marshall Brickman in Susan Brady, "He's Woody Allen's Not-So-Silent Partner," New York Times (21 Aug 1977) as "Showing up is 80 percent of life." On inquiry, Allen confirmed that he'd said the quotation above in a letter to William Safire (1989). More information here.
