This definitely seems like a "competing needs" thing. People repeat the advice that helps them, but different people need to adjust in different directions. "Look before you leap" versus "he who hesitates", I suppose.
There's an interesting result from studying people's prediction accuracy in which they improve simply by being asked to think about their answers and whether they're sure. For me, overthinking often leads me to explain away 'irrational' reactions that were quite accurate, but taking at least one extra look to say "has my first reaction missed something fundamental" is a lifesaver.
For me, my gut has generally been more right than my over-analytical mind. But I have a number of friends where I think it's the other way around.
