Doubt many are actually trying to "save you from yourself"; more like trying to provide another point of view - of yourself and/or your output - which may or may not be useful to you.
Re. "the odd thing...", I've personally found that many of the things that people value about me never (ever) crossed my radar until... Well, until some accidental or on purpose learning happened to me. I'm not actually proposing that I'm a dummy (!), rather that there's a whole lot extant than even really smart guys can't see all of and that of
course includes themselves and their circumstance.
I'm personally of the opinion that one of the greatest gifts we give each other is our (different) view of the other and all else. It provides to the individual a window and a stepping stone to different worlds with different rules, possibilities, realities.
