What this quote means

Learning a foreign language is like opening a window onto your own house. By seeing how others structure the world, you become aware of the peculiarities and riches of your own language, often invisible through habit. This quote invites curiosity and humility: mastery of one's language is never complete without the perspective of another.

How to apply it daily

Pick a language you don't know and learn ten words a day. Then notice how those words illuminate your own language.
