[Post 30] My bad habbit.

Since I was young, I have had a bad habit, which is nail-biting. When I was young, I did not think that it was a bad habit. However, when I saw others, who are nail-biters, I felt that it looked like baby. So I tried to remove the habit, but it was difficult. I was trying to put on manicures, and after that, I could, to a degree, put my bad habit right. However, I still have that habit, when I feel nervous and tension, such as during the exam. When I was in that circumstance, I became a nail-biter unconsciously. So, I am still trying to put that habit right.
