Mr.Mukoyama said that from that time, he became to be conscious about "professional eye contact".
That is the same sense that I felt at his seminars.
The story is just based on my memories so I'm afraid that the details of the story are inaccurate. He told me the name of the band and guitarist but I'm not sure about these anymore.
Anyway, after hearing this anecdote, I became to be focusing "the eye contact" more consciously. If you want to be a super professional and you'll get money to show something in front of the people, you have to make efforts these things including eye contact. If whether you are an idol, a comedian, a magician, a lecturer, a teacher, you have no exceptions as long as you are a professional.
During your lecture, I think you made eye contact with me many times.
Recently I become to be told like this at last.
I'm glad if I've become to get a skill of eye contact even slightly.
