Day 13

Following on from yesterday, you get used to another language through exposure. And exposure involves, intensity, duration, acceptance and type of exposure. And so you try to optimize those factors.

I don't think that you can do this by a formula. It is more of an art. You need to use to use your intuition as to how to go about it. Which is on a day-by-day, case-by-case. Individualized too, it goes without saying.

I like the AJATT (All Japanese All the Time) quote:

You don't know learn a language, you live it. You don't learn a language, you get used to it.
