I believe a lot of self-help fixing can be as easy to fix as it was to get "wrong" the first time. A behavior/habit takes 3 week/21 days to either lay down/make or replace (you can't just stop a behavior, something else has to take it's place so it helps to think of a "good" thing to replace a "bad" habit. I read about someone who bit her fingernails so she put nail files around at all the places she sat/was and instead of biting her nails she'd groom them instead. We learn how to brush our teeth, make our bed, etc., I think most of behavior can be broken down into habits sort of like that. That's kind of what DBT seeks to do? http://www.dbtselfhelp.com/html/dbt_skills_list.html
