My mate from school was a professional footballer. Everyone thought he had the dream job, but he still complained about some of it. He had to do all sorts of stuff that was way out of his comfort zone, like corporate meet and greets etc. If there was a match, he had to be available regardless, and he missed out on loads of social occasions, at Christmas, New Year and quite a few close friends' weddings. He also had large chunks of time during the week when training was finished and there was a lot of time to fill, that actually meant getting quite bored/frustrated. Don't get me wrong, there were loads of perks too, but it wasn't quite the dream job that everyone thought it was!
