Advice that you can't apply even if you tried. (Someone please think of a pithier name for this category of advice.)
Discussion:
Things that don't work even if you tried? Well, if you did try, you might find that there is some value in each of these, although not perfect value, whatever that may be. Value for you, by the way.
"Thinking ahead" means using your imagination. Sometimes there's more historical fact hidden in there than you thought. I frequently fail to do this, and often realize how much would have been saved if I'd done it.
"You shouldn't make value judgments" ... on behalf of other people whose real values you have no way of guessing accurately. Unless you like making an ass of yourself. Maybe the advice is better worded "making value judgments on behalf of others is like mind reading, so expect similar results".
"Do it wrong versus do it over." Yes, sometimes the meanings of wrong and right don't mature until the end of the first try, but neither is this an absolute rule. Yesterday I rushed putting up house wrap because I thought I could finish in daylight, and I overlooked something important. I'm now at a net minus.
"Trust the experts." Whom to trust amounts to a value judgment. Experts frequently have more knowledge on the subject than non-experts, so it might be worth a listen at least. If you can discern facts from advice, you're set up to benefit from this arrangement.
Actually, the idea is not that these are bits of advice that don't work even if you try them, it's that you can't even try them if you try. I think usually this kind of advice is given ex post facto, when it's easy to see what would have been good to do. Maybe something like non-deterministic state machines. At the time, it was hard to see what would have been good to do, and there's no easy rule of thumb that could have helped you right then to see the good path that became so obvious later.
What I'm not getting is why you can't try them.

The title of this page reminds me of the wonderful title of a famous Arts & Crafts pamphlet by WilliamMorris 'News From Nowhere'. I always enjoyed the Garden City movement piece entitled 'Nothing Gained By Overcrowding' too! -- MartinNoutch
