When I was at school all I wanted was to become a pilot. The long and short was my father refused to let me do a scholarship with BA and I had to do medicine.
I am now in a job that pays far more than flying, does not require a medical, and everyone I know who isnt a pilot says how right my father was. I have even been able to fly rotary.
Given the chance again, I would fly without any hesitation, and not a day goes by when I wouldn't give up everything to fly full time.
If you believe you would feel the same, go fly. If you have doubts dont. flying for a career is about passion over common sense. And yes I look up every time I hear a plane
