After saving $500, Dale Carnegie quit sales in 1911 in order to pursue a lifelong dream of becoming a Chautauqua lecturer. He ended up instead attending the American Academy of Dramatic Arts in New York, but found little success as an actor, though it is written that he played the role of Dr. Hartley in a road show of "Polly of the Circus". When the production ended, he returned to New York, living at the YMCA on 125th Street. There he got the idea to teach public speaking, and he persuaded the YMCA manager to allow him to instruct a class in return for 80% of the net proceeds. In his first session, he had run out of material. Improvising, he suggested that students speak about "something that made them angry", and discovered that the technique made speakers unafraid to address a public audience. From this 1912 debut, the Dale Carnegie Course evolved. Carnegie had tapped into the average American's desire to have more self-confidence, and by 1914, he was earning $500 (about $ today) every week.
