Every one of us does better when we know that someone thinks we can succeed. It's Psychology 101, and a knowledge nugget often overlooked by flight instructors when teaching students.
The next time you're with a student, send the message that you have confidence in his ability to learn a challenging task. Remember, you've already won your Oscar, so now prove that you deserve it. Tell the student you are sure she'll eventually master the skill at hand. Be positive when a learning plateau looms (which it will). When students express doubts about all the skills they have to learn (and they will), tell them you have no doubt they can learn them all if they press on. Let them know you're on their side. Then prove it.
Showing confidence in a student's behavior is one of the most powerful forms of inspiration at your disposal when you desire to inspire.
