I guess in a way taking courses from experts can make one more excited about flying, and make flying a comfortable experience. I know a lot out there love going to new places. But, sometimes the actual travel method can be a bit too much. Imagine 15 hours straight flight. It can wear out one's body, it can drain the mind. Having a positive outlook to flying can help alleviate all these travel-related stress. (I guess flying business or first class would help as well!).
Knowing the ins and outs of the aviation industry could possibly help. Sometimes it's all in the mind. And, that is a pretty big thing to conquer.
