All of the above reasons are very true. But the sole reason that I became a pilot was for the fact that since childhood, I have dreamed of never growing up or having to work for a living!!!
My father (also a comm pilot) really hoped that I might have strived for a more respectable career...ie...a drug dealer.
But seriously, it has been in my family for generations. My great Uncle held license #13 and was taught by Wilbur himself! My father's father flew P-47 in Burma in WWII. My mother's father was a private pilot, and actually drew up the original electrical schematic for the B-17G! The list goes on and on!
Good luck to us all!!!
