Irwin Gootnick M.D., is a psychiatrist who feels the causes of our issues are straightforward. Overeating, lack of confidence, trouble with relationships, and trouble with success are just some examples he cites as challenges that can be overcome. He gives understanding of the roots of these behaviors and offers advice on how to overcome those behaviors. Looking to childhood events and the guilt associated with the child attempting to meet its own needs, he believes, leads to unwanted behaviors as an adult.
