actually i didn't practice well becase of my lazyness.
so, i made up my mind when i watch the documentary which prested someon who are master of study. i feel like that i have to study more and i have to practice again and again!
i think im really lazy boy. because i didn't come to study home often. so i think i have to come to study home once a day! anyways it's very good for my english speaking level. and i felt it was great!
