I get people who succeeded preaching their view on what made them succeed (even if it often mis-attributes luck to spurious factors). But what is the recent trend of people who haven't even succeeded in their field preaching about what it takes to succeed and being listened to? Youtube videos, that coding career book that was posted here recently, this incubator, etc. I mean, I get the Dunning-Kruger effect as to why they preach but why are people paying so much attention to them?
