To my wife Penny who , in her desire to avoid public attention , goes otherwise unrecognized . As a Psychologist , deeply committed to her craft , her breadth and depth of knowledge continues to astound me and is woven through these words . Your faith in me sustains me . I am also deeply indebted to my clientele . As a medical student I was told they would be my greatest teachers . At the time I did not begin to appreciate the fullness of the gift coming my way .
