Crossing the overpass over Showa Dori one rainy afternoon, I resolved to learn 10 languages in my life. At the time I was struggling with basic Japanese, and it seemed a lofty ambition.

Studying Algorithm
Frequency (one hour per day)
Mode (reading, writing, listening, speaking)
Purpose (New Acquisition vs Maintenance: 3/1.
Priority, importance, ease.


One out of 4 lessons can be conducted on Duo Lingo. This is a great platform, offering a range of badges as motivation. It tracks your progress with sharp analytical reports. If you study for two consecutive days, you get a "wildfire" badge. Duo Lingo even has its own virtual currency, called the Lingot.

One hour of study equals 100XP on Duo Lingo, or a one hour lesson on iTalki!
