what's the worst betting advice you ever actually followed?

we've all got that one tip we acted on and still think about. mine was "always take the points with the home dog" - sounded sharp, cost me way more than i'll admit before i realized it was just something a confident guy at work said.

the worst part is bad advice always sounds reasonable in the moment.

so be honest - what's a piece of betting advice you actually followed that you now regret? bonus points if you still hear people repeating it like it works.
