You're making assumptions that aren't necessarily true. For instance, I'll avoid play in order to enjoy some idleness. I've figured out why I think; because I don't want to lose track of time, then have to go to work. The same reason I can sleep fine before my day off, but not before a work day.

I don't even think I hate my job that much. I'm not really even working crazy hours; yet it still seems like there's no free time, and I don't want the little time available to fly by.
