Advice to a fool is a fool’s errand. I’m a teacher, so giving advice is both a habit and an occupational hazard. It’s a hazard not only because the wrong advice ricochets. It is remarkable in retrospect how often my advice has not been wrong, and sometimes that was downright dangerous. The biggest risk is good advice which is resented. Everyone loves a slacker who can be ribbed (no ego risk there), but the blowback on a schmuck who turns out to be right can be fierce.
