KM personaly I compare my job to other professions depending on whats being compared:
Study and dedication - Surgeon. Surgeons like pilots must have an extremely in-depth knowledge of every facet of the job, and keep up with the latest changes.
Ability and skills - Concert pianist. Both must have excelent and well-honed manipulative skills after years of practice.
Financial ambitions - High class callgirl. If Im going to be screwed by an ugly employer in crap conditions then your going to pay me BIG money. And just like a callgirl Im medicaly checked every 6 months!
