How your son feels about himself is probably one of the most important topics to discuss because it will affect — positively or negatively — everything he does. As a parent, you can nurture positive self-esteem in your teenage son, but other influences outside your control also affect him. Your son's self-esteem during his adolescent years will stay with him and have an impact on the man he becomes. What you can do as a parent to nurture an appropriate self-esteem is also important and something that he will live with for the rest of his life.
