I want to be fluent in English, so I decide to speak English only. I'm listning to news in English, speaking English, thinking in English, and so on.There are people who become fluent in Japanese for a year. So I can do it. Speaking of thinking in English, as I'm thinking about something, I use Japanese. It's bad? I should do English? I'm Japanese and I've never lived abroad, so I don't know hou to think in English. It's very difficult to be fluent in English. :(
