Follow-Up:
there is still little on this subject with much speculation. however, i may be able to help you with your friendīs problem as i am in the middle of writing a book on personal experience and telling the world WHY did i do such a dumb thing! i need to know what area of work your friend is in and how successful he is. also info about his relationship with women as this could be a major factor. his childhood plays a big role too with his relationship with parents and praise. hope to hear from you. neil dawson
