I still flight instruct. It is nice. . . But I do let my students know in advance that my "real job" must come first if they want to fly with me. It is funny, because I now have more students that want to fly with me I think because I'm a (and let me use this word very loosely) "professional Pilot".
I do bring a lot more real world to the table than the other flight instructors on staff though which I think students really do like. The flight school likes to have me there because it helps in marketing that they have real world "drivers" as flight instructors.
My bosses also like it because it adds to my TT time and experience!
I like it because I would be at the airport anyway just hanging around, so now I at least get to get paid for it! I also see it as part of my way to "pay it forward" to the next group of folks out there!
