Just a couple of general thoughts that haven't already been expressed.
First, the problem with having too much time to think is that you can think your way into trouble.
Second, I'm hard put to remember any menial jobs I had that did not have a certain amount of Zen-like attitude on my part, mainly along the thinking lines of "how could this be done perfectly?" or "how could this be done differently?"
I have had those jobs, like Architect, when I was young, everything from collecting garbage, cleaning restrooms, raking leaves, chipping ice, (reducing 320-pound cakes down to 40-pound blocks), roofing, plus a bunch of work in trades like carpentry, plumbing and electrical which involved learning quite a bit so perhaps were not menial at all. Every job got analyzed, with suggestions for improvements that were sometimes accepted and other times were groaned at with a comment similar to "just pick up the goddamned garbage cans, whydoncha?" So eventually boredom sets in, and in the absence of ponderous thoughts, and in the presence of evil companions, much hellraising got planned and executed. Your mileage may differ, but the combination of menial work and evil companions produced a classic misspent youth. I really should have been dead or in jail a couple of times, simply got lucky with each toss of the dice. I was, of course, an undiagnosed INTP channeling all of it into the Rebel without a Clue format.
