Dumbest career advice you've ever heard?
I'll start - "if you are smart, hardworking, you will make it in this industry"
Having been in this industry for several years, I can tell you the number of people who falsely believe that all it takes is "smart" and "hardworking" to make it - usually, those people aren't really that smart or hardworking to being with - they may have gotten one okay-looking degree (never serial top achievers) and work long hours (but not smartly). Typically also come with lack of independent thinking and therefore only able to repeat catch-phrases that sound about right to them.
Most of the people I've met in my career who are dumb enough to believe it did not make it - phased out pretty quickly at / after associate level.
Curious to hear what other common dumb advices people give / believe in
