I prefer students who are self-motivated. I refuse to teach a kid dragged by the wrist by a zealous parent. I also do not teach beginning guitar, nor styles outside my realm of expertise. I offer old-time banjo lessons too, and mandolin. Being this selective cuts down on my teaching hours - but that's ok.
Time is a precious commodity.
I also have been teaching more in the music camp world. In 2001 I will be teaching at Puget Sound Guitar Workshop. Camp is a great way to encounter music. You are part of a small village for a time, and learn from each other in the best way possible. It's much more satisfying than sitting in a field of lawn chairs at a huge festival, getting your ear drums blasted and your nose sunburned.
