i realized that i could listen a little what native speakers said. i could not catch what restaurant and shop staff said before. but now i can a little bit. maybe thanks to classes and working.so it means there are no waste of time.finallly i realized it. ohh im confident. and my friend who can speak well said to me " you and i have almost same ability to speak English." i almost cried at that time. so im worry about my next situation because i think the oppotunity using English will decrease after i graduate. so i have to look for another comunity to talk a lot in english. i think my workplace is not sutable because there are some japanese who usually talk in English.im thinking about looking for some partners as a language exchange. but i know it has a lot of trauble.i hope my next roommate will talk a lot with me.and if they can i want them to introduce me to their friends. but my top priority is working here and saving money to go to NY. so if i use a lot of money its not good for me. so i manage to control my balance.
