I believe many of us are constantly asking advice from others, it happens that some of this advice doesn't apply to every situation. Then there is the inevitable Horse$#1t of advice, that just never stood a chance. So what game development type of advice have you received, that turned out to be completely wrong, it must be advice you tried to follow. Keep it friendly and with no names. 
Bad:
"Publish all the games you make"- This was by far the worst piece of advice I have ever followed. Read it in a article where a developer mentioned that they published their first game they ever made and it made more money than the rest of their games. What I didn't know at the time, was that was the developers first finished game; not first attempt at a game ever.
Foolishly I uploaded every attempt, ruining my own developer reputation before it could ever takeoff. It never recovered and I publish under a different name these days.
Good:
"Why not consider hiring? If this is something you want to say "all content created by me" but if you're just needing better sound, hire some one!" This is the short version of it but it was the advice that send me down the right path. For years I had this "Engines are bad, do everything yourself" mentality. Then this advice about sound, something I didn't consider important at the time, made me hire my first team member.
It was a small step in the right direction that allowed me to break past my own stubbornness. It still took five years after that for my first taste of success.
So any experiences you are willing to share?
