Enthusiasm! Most of the rotor jockeys I have had the pleasure of working with have been full of life, full of beer and full of opinions. Every pilot has his/her own ideas and is willing to fight for them, but is still willing to learn. (Most anyway) The people are the best part of this industry but there is also the personal satisfaction of having a great flight and knowing that you have done a good job, even if nobody else will ever know of it. Oh, yes, and the scenery.
Have a safe and happy Christmas and all the rest ....
