The nice thing about dentistry is that your success in the field is entirely up to you. Unlike making 200K as a manager at GM or Enron or KMart dentistry won't have you waiting to hear if you are going to get canned every week. Sure, your are going to have to worry about getting butts in the chairs but that isn't dependent on other peoples decisions, it is based on your direct influence on your business. It is like team sports versus individual sports. Playing on a team you are always worried about everyone else doing their jobs, when you are out by yourself you just have to worry about doing your job. But then again if you are the type of person who just tags along on other peoples accomplishments, you might be better working for a dental mill.
