Reflection of the latest video interview.

1) Actually, It has been always hard for me to answer questions in an interview without enough preparations, because I barely know vocabulary, so I am likely to fully prepare for it in advance. However, I couldn't do at this time and I had to answer poorly.
2) I am apt to be afraid of making mistakes in speaking English. That is way I prepare something like an interview with obsession. But, it makes me depressed and lose interest in English. From now on, I decided to push myself to make lots of mistakes without obsession!
