Earl Nightingale co-founder of Nightingale Conant was The Dean of Personal Development and author, dealing mostly with the subjects of human character development, self improvement, motivation, and meaningful existence. He was the voice during the early 1950s of Sky King, the hero of a radio adventure series. Later, his radio program Our Changing World was featured on over 1,000 radio stations for 30 plus years. Nightingale was the author of The Strangest Secret, the first spoken word record to sell over a million copies. Hundreds of his five-minute radio programs and selected segments have been compiled into the 21 hour audio program narrated by Joe Nuckols, The Secret Advantage.
Discovering these words from Napoleon Hill, Earl Nightingale found his purpose.
