TIP: Pick up a book on business a successful practice has little to do with how good a practitioner is and more to do with equipment within practice and how it is run.
TIP: CODE OF ETHICS - in my opinion you have to be stupid not to comply to these on a daily basis just by being a decent person and looking out for you patients. so read them, understand them and live by them. easy!
