IFSD, I recommend you don't repeat your "being a teacher" tosh within earshot of any teachers. You're likely to get a hiding if you do.
nottelling, do you
want to teach? If so, go for it, and the best of luck. If not, don't. Your days will never end at 3.15 if you're doing the job properly (extra-curricular, planning, marking, etc.) If you're just doing it for the time off, you'll never be much use - if you survive at all. And if you can't cut it in the classroom, you'll never be much of a flight instructor.
Teaching is an underpaid, under-respected profession that carries a great responsibility - shaping the minds of the next generation. Yet there are still those who see it as a stopgap, a fallback or a position of last resort.
