Insight is the smallest unit of truth that is actionable. If you cannot act on it, it is just an abstraction.
This reminds me of what I wrote a few years ago in the article sharing my internship experience at AppWorks. "If you learn things only to get competitive advantages over others, the things you learn are just lifeless knowledge. You cannot solve anything with that." Though I wrote this years ago, I still fell into this trap a lot.
