You don’t need a perfect language learning routine

Some of my best language learning material came from a random book I pulled off my library shelf. A history of Portugal, a book about Prague, a Swedish novel. A little Portuguese here, a little Czech there, a little Swedish, and it all adds up, like snow that slowly covers the ground. You don’t always need two free hours to make progress. What’s the most useful thing you’ve found by accident while learning a language?
