The stone cold truth of the matter is that most of the people pandering this advice are only doing so to build up their “guru” status ... They do this so that look up to them. They do this so that you talk about them (getting you to help them grow their audience). They do this so that you’ll feel like you’re somehow less than they are ... I promise I’m not going to do any of that to you.
Really? Just a couple of paragraphs down:
First off, you should know that your idea probably sucks ... It doesn’t matter what you think ... we’re not going to refer to your precious game-changing idea as “your idea” anymore. We’re going to refer to it as “your guess”.
Ok, so first he's telling you that he's the honest guy who would never bullshit you and really would never try to make you feel less than him. Then goes on to do exactly that.
To me that's an immediate red flag. I don't know the author personally and can't tell what his intentions were when he wrote his essay but I've had the past displeasure of dealing with sociopaths who showed the same kind of behavior.
