Fulltime employment is hell on earth. People only tolerate such conditions because they have a reason to do so. They have a family that they need to provide for or expensive hobbies. If you have neither it's only additional stress. They do it because they have a light at the end of the tunnel, they are willing to sacrifice their nerves/time/power for something they consider worthy of all these efforts. Without that there's no need for all that stress. Working is hell on earth, no sane person could enjoy it. Working is for most people a necessary evil, something you need to in order to survive. For someone who has no family/expensive passions there is no reason to do anything except the bare minimum.
