The fuel that works too well. "Clean fuel versus dirty fuel. It's very difficult to see. The car looks like the car from the outside. Very difficult to understand. Is it clean fuel or dirty fuel that's operating the car? And I mean, that car can go fast. It can take a lot of people with it if I'm on dirty fuel. And in some ways, dirty fuel is a more potent fuel in the short term for me. I get more stuff done quicker, and even sometimes with higher excellence, out of dirty fuel than I do with clean fuel. That fear is a heck of a motivator. [...] It's higher octane. The problem is that it's got all kinds of contaminants in it and you eventually torch yourself, and the car breaks down and you go off the rails and blow yourself up—whatever analogy you want to use." — @BrentBeshore on The Knowledge Project
