A. Do you feel nervous or worried about the stressful situation?

Yes. I always feel nervous about the stressful situation. But, continued period is comparatively short because I handle my stress well.  I have various methods. For example, I read a book ( books that I can easily read like Korean essay, novel), stroll my town and write a long long diary.

And sometime I meet serious problem, I have meditation time and meet my friends.
