Personal experience isn't important?? If that's the case then anyone on the net could teach this stuff. Without the experience one would only know how to save themself by a book, not learn what went wrong and how they fixed the issue. That might work where you dive where you have direct path to the surface but I don't know any cave diver who thinks personal experience isn't necessary.Personal experience is important, but it's less important than what you teach, how you teach it, and how well you teach it ...

If someone said that you don't need a Ph.D level education to teach high school math, would you equate that statement to meaning that no education is important and that the person was arguing that any kindergartner can teach calculus?
