My father once said that if you enjoy your job you're either deluded or not working hard enough o.o
Frankly I agree ... some jobs sounds wicked on paper, but when you think about them they aren't as desireable.
I mean travelling merchant liaison; lack of sleep, constant jetlag, plane food, hotels, lack of true friends.
Food critic; pissing off a whole lot of people who strived to give you the greatest meal of your life and half the time effectively tossing it back in their faces.
Astronaut; Years of training and study for only the opportunity to be selected.
Pilot (personal, domestic or international): Way too much time spent in airports, increased risk of deep vein thrombosis, chance of sitting next to that one guy you possibly hate the most for 11 hours + on longer flights, having to sound chirpy over a PA system when all you want is a drink and a freaking cigarette.
Professional athlete/coach: years of repetitive training drills, absurdly early hours, constant need for fitness regimes, personal nutriotionists making you live on a tasteless diet, constant yelling and screaming, bearing 11+ sweaty arsed players in a crowded ready room after play, people running your name through the mud if you screw up on a single game.
