Giving up forcing me to use English

I gave up trying to use English as practical use. It takes me a lot of time to read some sentences. If I read a book, I'd need 1 hour to read 1 page of text. And besides, It have also taken 30 minutes for writing these four sentences. I'd waste a year if I try to read a full book. 

I decided to use Japanese for reading, studying, writing, etc. I can use Japanese ten times faster than English. I abandoned the idea of managing to balance studying and using English. I will only use English for studying English. I should concentrate also.

I want to be able to use English well as soon as possible. But I'll go easy on me.
