In this question, Professor Han Duck-hyun, author of the book, says “he also feels anxious too.”
He is a sports psychiatrist who has long coached sports players who live with extreme anxiety and tension. Of course, he has been meeting a lot of ordinary people who complain of anxiety. Based on his study and experience, we can properly understand what anxiety is and suggest the right way to control anxiety.
He also says anxiety is the basic emotion that human have and if we can manage it properly, the feeling of anxiety itself does not matter. If high self-awareness, including anxiety, can be harmonized with positive attitudes or flexible thinking, it can rather help overcome the problems at hand and grow one step further.
