Have you ever thought about why are you becoming the kind of a person as you are rite now? Most of the characters that build us; the way we think, do things, conduct ourselves.. etc etc, are like the cause-effect of what have happened in our life. Family, education, friends, love life, work life... just life we have been through.
Just try to think about one of your habit or one of your character. Think carefully and ask yourself, why do you react/ and do things with that way? (say, you get angry easily or you don't get angry easily.. a pessimistic or an optomist). Not only saying about bad stuffs, but your characters as a whole.
Now I know why Dr. Phil is good. Notice what he does? In every problem, he digs to the source of the problem. Like I watched one show before, a wife had a tendency to abuse her husband (yep, wife to husband), whenever he got drunk. The more she abused him, the more he wanted to get drunk so he wouldn't feel the pain. She didn't know why. The more Dr. Phil dag into her life.. one answer: it's a cause effect of her past. Her dad was an alchoholic, and as a little girl with hatred to her dad, she couldn't do anything.. so there she was, with abusive character to her alchoholic husband (and she was a nurse!).
You don't need to go Dr. Phil.. just examine yourself/ others (not judge!) carefully. Most of them we don't realize, you'll be surprised what you learn about yourself and others. Let me know if I'm any near to being right ^_^
