Excellence is a talent or quality which is unusually good and so surpasses ordinary standards. It is also an aimed for standard of performance.

The Ancient Greeks had a concept of arete which meant an outstanding fitness for purpose. This occurs in the works of Aristotle and Homer. Aristotle once said. "We are what we repeatedly do . . . excellence, then, is not an act, but a habit." Another related concept was eudaimonia which was the happiness which resulted from a life well-lived, being prosperous and fulfilled. The equivalent concept in Muslim philosophy is ihsan.

Studies have shown that the most important way to achieve excellent performance in fields such as sport, music, professions and scholarship is to practice. Achievement of excellence in such fields commonly requires approximately 10 years of dedication, comprising about 10,000 hours of effort.

Earl Nightingale (March 12, 1921 – March 28, 1989) was an American motivational speaker and author, known as the "Dean of Personal Development." He was the voice in the early 1950s of Sky King, the hero of a radio adventure series, and was a WGN radio show host from 1950 to 1956. Nightingale was the author of the Strangest Secret, which economist Terry Savage has called “…One of the great motivational books of all time“.

When Nightingale was seventeen he joined the United States Marines. He was on the USS Arizona during the attack on Pearl Harbor and was one of twelve surviving Marines on board that day. Before being mustered, Nightingale was an instructor at Camp Lejeune, North Carolina.

After the war Nightingale began work in the radio industry, which eventually led to work as a motivational speaker. In the fall of 1949, Nightingale was inspired while reading Think and Grow Rich by Napoleon Hill. Quoting from the Earl Nightingale official website: "When he was 29, Earl's enlightenment had come to him as a bolt out of the blue while reading, 'Think and Grow Rich'. It came when he realized that the six words he read were the answer to the question he had been looking for! That, 'we become what we think about'. He realized that he had been reading the same truth over and over again, from the New Testament...to the works of Emerson. 'We become what we think about.' 'As ye sow, so shall ye reap...'" In 1956 he produced a spoken word record, The Strangest Secret, which sold over a million copies, making it the first spoken-word recording to achieve Gold Record status. In 1960, a condensed audio version of Think and Grow Rich was narrated by Nightingale. It was titled Think and Grow Rich: The Essence Of The Immortal Book By Napoleon Hill, Narrated by Earl Nightingale, produced by Success Motivation Institute. Also in 1960, he cofounded the Nightingale-Conant corporation with Lloyd Conant.
