Larry Vaughn, an undiagnosed dyslexic, built his career in commercial print on the principle that business thrives on cooperation, ethics, and mentoring. In his memoir, Business Cards and Shoe Leather, Vaughn details how, without the ability to read or write, he founded two premier, international business cooperatives: DSCOOP and thINK. When, as an adult, he finally learned about dyslexia and taught himself to read, Vaughn realized he had been helped all along by the positive aspects of dyslexic brain wiring.
