Too many CFI candidates think that the rating is about learning to fly from the right seat while talking. Not really. Sure, you need to learn the manuevers and how to fly from the right seat, but the commercial rating already proved you can do that - you just have to train your hands, feet, and eyes to deal with the right seat.
People are people, and that hasn't changed, and probably won't, not for a long time. What you have to do is learn how to get inside your students' heads and find out what motivates them so they do the right thing. Further, you need to find the analogies and words that take your students from rote learning to correlative thinking. This is very important because cannot possibly teach your student everything about every situation; they will have to think on their own to make correct decisions and judgments. Remember, no one ever taught Al Haines and his crew how to fly a DC10 without hydraulics or Captain Sullenberger how to land in a river in a dead airplane.
Please note that the thinnest of the Gleim books is the study guide for the fundamentals of instruction. The ironic part of that is that, to waive the requirement for the knowledge test on FOI, you need the equivilent of a master's in education. Don't ever forget that, first and foremost, you will be an educator that teaches someone to be a pilot NOT a pilot that happens to teach.
At the same time, you have to work to be the best possible example you can be. No short cuts - a preflight every time, a weather briefing before every flight (not just the first one of the day), no fudging airworthiness. Remember, your students will fly the way you do and everyone will see you, whether you know it or not. As a CFI, you're on something of a pedestal, whether you like it or not.
Likes and dislikes as an instructor?
Love students that prepare and read the material. Don't like students that try to take over the syllabus. I'll be happy to discuss things, but I am the one that's managing the process.
I love and hate Flight Simulator - love it because it's a good procedures trainer; hate it because we have bunch of sel-trained instrument pilots and it's hard to change the habit of staring at the instruments.
Love inheriting students from good instructors. Hate fixing students that have had poor initial training.
- Love students that take it seriously. Hate it when students say "close enough..."
