What if You Did More Than Two Hours a Day?

In my family, we've gone in the last three years from being a monolingual family to now at varying levels depending on the student. We're starting the study of our six and seven languages. What if you did two hours per day? Two hours per day times 300 days per year over 12 years, that's 7,200 hours. A student could very feasibly learn Italian, 600 hours, Greek, 1100 hours, Hebrew, 1100 hours,. Korean, 2,200 hours, and Arabic, 2,000 hours. It's just that most people don't have the interest or system to do it.
