The author of this blog-post comments on how this seems intuitively sensible, which I agree with. The more people I meet, the more different they are, the wider their world-views, and the more we interact, the more I feel that I can think “between the cracks” of the different knowledge domains.

So the lesson here is: meet and get to know more crazy, different, interesting, unusual people. You’ll have a much higher chance of having your own interesting thoughts!
