The Defense Language Institute — or simply DLI to the many Department of Defense service members and civilians who have gone through foreign language training — is renowned for being one of the most prestigious and rigorous language schools in the entire world. Every year, thousands attempt to make it through the exhaustive 26 to 64-week courses, which consist of five days a week of in-class foreign language study that lasts seven hours a day — plus two to three hours of homework per night. The formidable 98% native speaker instructor cadre teach over two dozen languages at the Defense Language Institute, and due to the extreme difficulty of the programs, student pass rates are dismal.
Benjamin Franklin nailed it when he said, "Fatigue is the best pillow." True story, Benny. There's nothing like pushing your body so far past exhaustion that you'd willingly, even longingly, take a nap on a concrete slab.
