Does that "most" mean 60% of people, or 90%?
Unsolicited advice only annoys me if it's long-winded and preventing me from doing something else.
Also, I don't know what "validation" is in this context. Oxford English Dictionary doesn't seem to adequately cover psychobabble (though it does at least have the word "psychobabble").
Most people just don't like advice they didn't ask for.
