A friend of my parents was a professor, lecturer and author in biology. One day, he was fed up and became a Tram Driver.
I'll never forget how he explained the bliss of coming home, dropping your company-bag in the hallway only to pick it up next day before going to work. How he never had to read up on recent insights in the field of driving a tram on weekends. How he was finding joy in reading biology-books in the evenings, free of any pressure, again.
(If this sounds denigrating to a tram driver, it is not meant as such, at all)
