Surely,if you have to ask others that question,it probably isn't worth it for you.There seem to be two main types of pilot.There are those who eat sleep and live it(although many are reticent at expressing their keeness)and others who just see it as a job and can't wait for their pension and the golf corse.The training/money hurdle has probably not disuaded the eat/sleep/live types from from pushing on and trying to get into the industry.It might have disuaded the jobbies.
I'm a keenie..but I still moan about things.I couldn't imagine doing anything else.
Just remember,you are only here once.It is no good lying on your death bed saying..I wish I'd been a pilot.
