Learning a New Language
Time Required: It takes 600 to 750 classroom hours to fully learn French, Italian, or Spanish; to speak proficiently in a year, you should spend at least 2 hours a day studying.

Where to Find It: On average, we spend almost 5 hours a day simply relaxing, thinking, or doing other leisure activities. Spend half that time conjugating verbs, and you’ll still have 2 hours to chill.
