Learn Languages

To have another language is to possess a second soul.
- Charlemagne


I love learning languages. It is the best way to make friends from different cultures. A whole new world of literature, songs, films, and news open up with each language. A foreign language also exposes you to local foods and their authentic recipes.

The following is the list of resources that I have used to study each language. Because my native tongue is Korean, I mainly learned Japanese and Mandarin Chinese from resources written in Korean; however, I included some resources in English that I found helpful as well.
