I MUST IMPROVE ENGLISH

I began to study english 15 years ago, but I did not love it. I studied it to pass exams, but not used it. So after graduated from school i forgot english quickly.
But now I have to learn it again, because there are many foreign clients in our company. English is the international language, so we can communicate using english. My manager let me translate same files not long ago. The second morning I sent the english files to him. the noon he said: "it spent me as more time as I translate it myself". I felt very sad to hear it, but said nothing. At the moment,there was a strong feeling that I MUST improve my english FROM NOW ON.
I must learn englih, not only this moment, today or tomorrow, but everyday. LEARN ENGLISH EVERYDAY, STEP BY STEP.
