Our club used to have "instructor night". Two or three instructors would be at the field and help whoever showed up. It was nuts; with, at times, 4 or 5 students standing in line waiting.

Now it's the student's responsibility to contact an instructor (they're given a list of names and numbers), and set up date and time that are good for both. It makes things much easier on the instructor(s). You can take on a new student if you want, or not. You can fly on your own Tuesday, or help a new guy.

Our club's best instructor hasn't even flown for about 4 years now. He would train students, 4 or 5 a night, 3 to 4 days a week, May through October for two or three years. Never said no; if he came to the field and was asked, he'd help.

You want to talk burn out? Don't risk your enjoyment of this!

Just my thoughts.
