《語言的突破(英文原版)》主要內容：DALE CARNEGIE BEGAN teaching his first public speaking course in 1912 for the YMCA at 125th Street in New York City. In those days, public speaking.was regarded as an art, rather than as a skill, and its teaching aims were directed toward producing orators and platform giants of the silver-tongued variety. The average business or professional man who merely wanted to express himself with more ease and self-confidence in his own milieu did not wish to spend his time or money studying mechanics of speech, voice production, rules of rhetoric, and formalized gestures. Dale Carnegie's courses in effective speaking were immediately successful because they gave these men the results they wanted. Dale approached public speaking not as a fine art requiring special talents and aptitude, but as a skill which any normally intelligent person could acquire and develop at will.

Today, the Dale Carnegie courses circle the globe and the validity of Dale Carnegie's concept is attested to by thousands of his students everywhere, men and women from every walk of life, who have successfully improved their speaking as well as their personal effectiveness.
