When you have to persuade someone who has more control than I do. I feel that I have to speak well.
Usually, you're a boss, or you're talking to a major customer or a major partner. Especially, I think it's time to sit face to face with a conclusion that's fundamentally different from the other person's, when the power of the horse is needed.
I think we need to know how to arm ourselves with logic, how to touch emotions, how to figure things out first. I look forward to learning a lot from Moon Sung-hoo's lecture :)
