Les Brown was introduced to personal development and positive thinking at age 10 when he worked part time cleaning the office of a man named Mr. Sidarsky, who listened to the likes of Norman Vincent Peale, Earl Nightingale, and Ernest Holmes. Les loved to eavesdrop on the messages of hope and abundance.   In spite of being labeled “the dumb twin” and “intellectually disabled” in grade school, Les used the consistent messages of “innate greatness in all of us” to become one of the most beloved motivational speakers of all time.
