If you could find a source of advice for areas you need that is always bad, that would be amazingly useful. Each piece of advice is another pitfall you can confidently avoid.
Eh, I know you're being facetious but the opposite of bad advice is not good advice. Things are more complicated than that. Which is why even a 20% hit rate (say) could be very impressive.
If you can get multiple wrong takes on the same topic you can very likely narrow down the correct path by a lot. Even if each piece of anti-advice is kind of vague by itself.
Unfortunately, real life advice is rarely something you can short. :(
