What makes you think I can't discern what can be changed and not? That I point out that external factors exist? That's not even what annoys me the most (even though it's true, in differing amounts and specifics for different people) of such "advice" - it's the no-questions-asked assumption that I should change myself for the person posting it. Essentially "You are not good enough, do as I say". But I suppose you will just answer with something about being annoyed about that saying something about me that I should change, or, now that I wrote that, something else about something else I wrote... What's wrong with letting people be who they are?
