By a personality-conversation teacher and lecturer who has concentrated on this particular drawback, this- if you are shy (and one out of two people are) will help you to become the REAL YOU. Why you're shy, and how shy are you (personality tests here); the assets and liabilities of this trait; your voice, vocabulary, conversation, and the way you look; social relationships, education, exercise, public speaking, etc., etc. come up for consideration, with literary and personal illustration amplifying the material, which is aimed at the lowest common denominator.
