People suck at taking advice. So sayeth the author of the book I am currently reading. He has amused me a few times already and I am only a few pages in. The part of that quote that makes me chuckle is the part of me that is trying to have a business based on my giving advice. And i have certainly noticed that often people don't take it. Even when they ask for it. They really (and this is probably for the best long-term anyway) just want to do what they want to do. And that is what they do.
I occasionally find it frustrating that they bother to ask for this advice in the first place. Mostly though I have learned that I need to reiterate these points later, note them for myself, and figure out how to say it to them so that they think they decided to do it themselves. And that is the crux of this thing I am trying to do.
