The bad part to me about jobs like that was how you were just spending massive hours doing stupid things. A lot of people would enjoy working 10 hours a day in a highly engaging, challenging environment. Instead everyone is so shot from overworking, stress, poor interpersonal relationships, etc. that it sometimes feels like you're working all day on a project nobody needs that doesn't work led by a manager who doesn't know what he's doing and doesn't care to. Basically like you're getting paid to get punched in the face rather than to do a job.

I honestly had managers at the Kmart retail store I worked at who struck me as smarter (and certainly more humble) than at least one software manager I've had
