> the way a language structures the world for you in the way its vocab influences the way you think in concepts

You can even see it in this article :)

"Learn only 4 tenses. Past for one time events, past continuous, present, future. These are enough to go by and explain yourself."

Some lanuages don't even have 4 tenses. Polish has 3. And Past Continuous isn't a thing, we have aspects instead.

BTW I don't intend to criticize the author, they're far more of a polyglot than I am (I only speak 4 languages, and only 2 well). It's just funny how we take some things for granted.
