“How does fluency happen? First and foremost, people who attain fluency practice a lot more than the typical foreign language student. “A lot” doesn’t mean 10% more, 25% more, or even 100% more. People who attain fluency practice about ten times as much as the typical person who is officially “learning a foreign language.” Sure, the quality of practice matters, too; immersion is the best method of foreign language acquisition. But unless you’re willing to give ten times the normal level of effort, fluency is basically a daydream.”
