'You can lead a horse to water, but you cannot make him drink'.
Randy, it seems crazy to me that people wouldn't take on board what you're saying. If they're not valuing the advice because it's free, then more fool them.
Perhaps it's time to put a cost on this kind of advice. That way, if their eyes and ears aren't open to see and hear the guidance you're giving them, at least you've not wasted your time for nothing.
