I think if you are committed to it, listen to the tapes every week, do the readings out loud every day, and continue to practice, then it is worth it. I know it is quite expensive, but if you are willing to stick with it, then you are basically making an investment in yourself. For a lot of people, overcoming social anxiety could open up a lot of career opportunities and provide an enormous return on investment. Plus, there is the emotional return on investment in being confident and, likely, more happy.
