I have an alternate point of view: my desire to remain engaged in an interesting and problem is high so that anything resembling monotony quickly bores and frustrates me. I question what I had done wrong in a previous life to be condemned to a latter day Sysiphian punishment. This is primarily why I rail hard against processes - they appear as manifestly unjust punishment.
In my opinion, our brains have a way of painting the bad old days in a nostalgic light. I would posit that if you were forced by circumstances to chuck boxes for 8 hours a day with company-specified arrival and departure times plus company-specified breaks, you would not relish it. But that's just my opinion.
As mindless as work like that tends to be, there is a kind of zen quality to it. I think the trick now is to find a hobby that lets me turn off the left side of by brain for a while to do something so simple, yet satisfying.
