Good advice. Also relax a little, don't be a super jumpy flight instructor. I noticed when I was training instructors getting on edge during advanced stalling etc.. When one is jumpy it results in a jumpy student. But I've also noticed it in several of my more experienced senior instructors as well. I really recommend aerobatic training even if it's just a couple of flights.
There's also the instructors that are too uptight, yelling, getting angry at students, that's not effective. When I was training one instructor in particular would rip the hell out of you while your flying (I had 12hours flight time) I wasn't paying $200 an hour to get screamed at so never flew with him again but also when I was working as an instructor numerous students would complain to me about other instructors that were upsetting them.
Good luck and I hope you get a job soon mate!
