My hat goes off to the people who love to teach. I honestly admire instructors who make it their careers to do it.
Me? I instructed full time for about a year before going to XJT. I learned an absolute ton instructing, but I just didn't really enjoy it. I like being an average line pilot; give me an airplane, and I'll gladly take it from point A to point B, collect my paycheck, and go home.
XJT was great experience but I got caught up in the furlough. I'm flying C402s now and love every minute of it. Best flying job yet. Go figure.
