“Failure is the condiment that gives success its flavor”

“Failure is the condiment that gives success its flavor” is a popular quotation that has been printed on many posters. American author Truman Capote (1924-1984) said in “Self-Portrait” (1972):
 
“Failure? Failure is the condiment that gives success its flavor. No, I’ve drunk that special hemlock, bit that bullet (especially working in the theatre) enough to now scorn it.”
 
The essay was reprinted in Truman Capote’s collection titled The Dogs Bark; Public People and Private Places (1973).

Truman Streckfus Persons (September 30, 1924 – August 25, 1984), known as Truman Capote /ˈtruːmən kəˈpoʊtiː/,[1] was an American author, screenwriter and playwright, many of whose short stories, novels, plays, and nonfiction are recognized literary classics, including the novella Breakfast at Tiffany’s (1958) and the true crime novel In Cold Blood (1966), which he labeled a “nonfiction novel.” At least 20 films and television dramas have been produced of Capote novels, stories, and plays.
