Beware the Metagame:
"The more abstract a subject is, the easier it is to reason about and therefore make progress on. That's why we've made a lot more progress in math and physics than any other subject."
I've first noticed this problem in the startup world where you see famous people that sell books, talk at conferences, and tweet advice to founders, but when you take a closer look, they've never done much founding themselves. They're like the "entrepreneurship" professor that never built a business. They're experts in the metagame -- they're polished speakers, engaging writers, and thought-leadering tweeters. The problem, though, is that they're not judged by customers, the market, or nature, instead they're judged by their peers. I call them metapreneurs.
