Learning a new language is like getting a second pair of eyes. You notice words you never needed before.

Another language is not just a second set of labels for the same things. It carries distinctions your own language does not bother making, and once you have them you start noticing things you had no name for before. Speakers of it become reachable too, including people you have walked past for years.

Ten minutes a day is a real amount here, more than an hour on Sunday. Pick the language you hear near you, in your family or your neighborhood or the kitchen at work. Twenty words and a greeting will already change one conversation this month.
