Related to receiving bad advice, that's actually a good rule of thumb.

As any kind of creative, especially someone that actually tries, you will receive bad faith or shallow critique eventually in your lifetime.

So my personal tip is, "Ask your critics to elaborate." Then, if it's not a legitimate place of criticism. You can watch them crumble like dust, make it about you versus the work itself, or pivot topics on a dime.  You know, the 'cuz I said so' types, who can't actually answer the counterpoints you raised. 

Because it's only truly the worst advice, when it comes from malice and envy.
