You spend 40+ hours a week at work, plus extra transit time. Get home, sleep eat, shit, family duties, decompressing etc, a lot of people don't develop lives outside and end up on park benches feeding the pigeons.
Fuck that shit. Life is too short for the grind. If you find a wonderful job, porn star, punching Justin Beiber in the face etc sure... but otherwise work is a curse. There is way too much better shit to do outside of work.
Unless you got OCD there isn't much that would still be good doing for 40+ hours a week for decades, aside from banging hot chicks and punching Justin Beiber in the face.
It is a sad thing if you can't enjoy not working much as it is working a job that isn't as good as the other options.
