Difficult to Continue Using English

As you know, to use English continually in Japan is difficult for Japanese, because using English is not necessary for us. And we can’t have any motivation using English in daily life. So they say that if you want to improve your English you should put yourself into an environment where you have to use English. I think that’s right. But it is difficult for businesspersons, because we have to learn or study new technologies and businesses. I wonder how to continue using English in my daily life. One solution is writing blog or twitter, uhmm but that is not suitable for me lol.
