This is a great read Bill and I think perspective students should read it. The flip side of the coin is that in what we do, most people will come and go. That's just how it is. We can design programs to keep people's interest, but there really is no way to keep people from quiting. That drives some teachers nuts. I view it a bit different. Those that quit do so for thier own reasons, some good, some bad, but in the end it is thier decision. Hopefully, for however long they have been in the school, we've helped them in some manner. I wish them luck in whatever the future holds for them. Now our attention is focused on those that have stayed and percivered. Those are the people that will learn the most and hopefully be the future of the art.
