Not enough sleep? A brutally painful (beyond OD-ing on Advil) back? Reading too much about maniacally action-oriented U.S. Grant ("almost inhuman disinterestedness in ... strategy"—Josiah Bunting, from Ulysses S. Grant). For whatever reason, in a Comment on a Comment re systems thinking, I called it "gentrified bullshitting."
I more or less believe it—but I surely shouldn't have said it so crudely, and it surely wasn't personal.
