If you love flying, pulling some Gs and taking the crate upside down - forget about becoming a professional pilot. You will be frustrated by the stupidity of the job and your idiot colleagues who are just so full of themselves.
If you are 4'11'', or you have an IQ equal to the room temperature in F but long for the social standing of a heart transplant surgeon in exchange for 1% of the surgeons training - If you also don't mind a very simple machine doing a better job than you and wearing itchy shirts with 'clip on' ties- professional pilot is the job for you.
