As a cram school teacher, I regard daily learning as my duty. I love learning actually, that's why I came to be a teacher. So it is fun and useful for work as well.
For English Vocabulary building, I use an app called MIKAN. I want to be a good communicater in English as in Japanese, that is, a true bilingual. Vocabulary is the foundation of thinking so I consider it crucial.
There are lots of things I don't know, besides information is hidden from our eyes especially in the fields of economy and politics. I believe every leader wants to cover their mistakes from the public even in a most democratic nation. Therefore we always need to stand on our toes cheeking every move politicians make. Japan is no exception, beware of the trends so that no war would make innocent people suffer.
