After

I usually read books or write a diary before going to bed.
Although I study English every day, I can't see any progress yet.
Considering I'm still not that old, I believe that I will get better if I keep doing it.

Before

Before going to bed, I read the book and write a diary.
Although I study English every day, I can't see any progress.
Considering I'm still not older, I believe that I will be better if I keep doing it.

잠들기전에 난 책을 읽거나 일기를 쓴다.
매일 영어 공부를 하는데도 아직 진전이 없다.
아직 나이가 많지 않다는 것을 감안하면, 더 노력하면 지금보다 나아질 것이라고 믿는다.
