You ever been wrong? Then you know why. If you have ever been wrong then you can be wrong again and you know what happens then, right? You fuck shit up. No, in order to get anything down right you can't just trust your own instincts and judgment, you need to have people around you sign off on your ideas. How many truly original thinkers do you know who have actually been successful? None, that's because original ideas aren't ever very good. They are like Kool-Aid in the packet, they need watering down or they taste horrible.
The problem is that everybody is flawed, we all have a blind-spot. Your original concept has a problem that anybody else but you can see and if you never actually share it with other people you won't ever find out. You have to let people dilute it to where it is palatable.
Had Timothy McVeigh run his idea by a bunch of other people his idea might have been diluted to some kind of Glenn Beck/Teabagger type of protest, instead he went ahead with the full-strength product and got his ass executed. The same thing went with Son of Sam and Ted Bundy. Success is about conformism. If McDonald's decided to put forth original, healthy, flavorful food they would be bankrupt in a couple of weeks. The ideas in your head have to be blanded out, have to be made into something with less flavor, less of your thinking and more everybody else's. They have to be dumbed down, simplified.
Ordinariness is your salvation
Anything else is to suppose humanity to be smarter and better than they ever are. "Success" and popularity are always the same thing whatever people tell you. In the end only the completely gray and common will win.
