<p>I dont  find it credible that professionals have difficulty when trying to to grow behavior. Obviously Robert Greene have tought  some of the strategies that can be used to help manage  behaviours. Many of others have been given us recently. In a tv comercial Philip Zimbardo show how to do this. I am also inspired by  Transpersonal psychology.I am not trained as a coach but I have been trained in Psychohistory.</p>
