This lingered around my mind a few times on unrelated stories. But couldn't find it later (not quickly anyway) as I had forgotten how it was named.

Title shortened & to undo exaggeration. Often referred to simply as "Helsinki bus theory".

Edit: A better source is linked at the bottom of the Medium article:

The Internet Archive had this also:

But I considered it unkind to have a HN submission hammer the IA.

I was expecting something about how, back in the early millennium. Helsinki replaced its original surface-level bus station with an architectually interesting underground one. Instead, this is a motivational article, formatted in LinkedIn-speak and as vapid as one of those classic Successories posters. Also a good example about how if content is hosted at Medium, it's probably not worth one's time compared to a classic blog.
