Really? I can't believe it. But if it's correct, I did it, even sometimes it was only 3 minutes of practice at a day.
I don't know if I can make any improvements, but I noticed one change. I got more conscious (nervous?) about my pronunciation. I read or heard somewhere that if English learner becomes more conscious about their pronunciation, they can't speak English, even very easy and short sentences. I kinda understand it.
