Hindi Language Study

Since 25th of August, I have begun to study Hindi language.
I take a private lesson 3 times a week, one and half hours for one time,the best of all is I can take that lesson during a working hour.
I can study another language and get money from that in a way,haha.
I am very interested in learning foreign languages.I can now speak Japanese,English and Chinese.
Learing Hindi language is very useful in India because Hindi is one of the formal languages in India and many of Indian people understand that.
If I can speak Hindi, it is not only good for my another language to evaluate myself but also good to know what local Indian people think.I can work more localy in India.
I don't know many Japanese people can speak Hindi language or speak 4 languages.
However, it take much time and need much patient to learn it....
