Yep. Approximately no-one has ever taken advice. Ever. Even when they ask for it, they use it to confirm whatever course of action they had already decided on.

(If they're actually bugging you with problems they won't act to fix, a useful method is to strip politeness and be blunt: give them a short list of actions before they next ask you about it and demand progress on these before you'll talk about it again. Then they'll either do something or stop asking. Usually the latter. Either is a win.)

You might think from the amount of advice given out that it was going somewhere, but there's a lack of evidence to this effect.

If you need to change someone else's mind, you need to actually sell the idea. And this always has to be done with a pull, not a push - attract them to your idea. This is not quick, but push just doesn't convince.

Note that you won't find their true rejection by bluntly asking, as they will detect "sales!" and go defensive.

(I am awful at selling things for money, but try to sell people on ideas more or less every second I'm writing or talking. How am I doing on this one?)
