I have a friend who is quite obviously way smarter than anyone else around. As in: I don't usually explicitly notice how smart people are, but when I first met him it was so plainly obvious to me like few things are. Anyway: at some point this friend decided all he needed for happiness were books and water, so he quit his law job and spent a year reading. Once that got boring, he decided to hire on as a tram driver, which they were desperately looking for at that time. He was rejected for this very reason. They have apparently seen quite a few people on this sort of career trajectory, and since the training is quite extensive, it hurt them financially. A year later, their need had grown even worse, or maybe my friend's dedication made them change their mind. In any case, he was accepted and, after six months of training, became a driver on his own local tram line. Six months later, he got bored and quit.
