We ALL do it for the fun..I am one of the professional pilots of which you speak, who just happens to earn a living from it. Hopefully we are ALL professionals--after all, it is just an attitude.
James Michener said it best:
The Master in the art of living makes little distinction between his work and his play, his labor and his leisure, his mind and his body, his education and his recreation, his love and his religion. He hardly knows which is which. He simply pursues his vision of excellence in whatever he does, leaving others to decide whether he is working or playing. To him he is always doing both.---
I will leave it for others to decide if I am "playing" or not....
Hex---welcome to the world of play....
