Jongholee, thank you very much for taking the lecture. As you said, I thought that methods that are difficult for presenters to change, such as 'don't be nervous' 'take a deep breath', would not work in real life. Rather, I thought that if the materials were well-prepared, the presenter's nervousness would naturally be reduced, and I created a lecture to incorporate such principles, and I sincerely thank you for recognizing this. As you said, I am also glad that you recommended it to your colleagues. I guess that means you thought it was a lecture worth recommending. Thank you again! :) I sincerely hope that I have contributed to improving Mr. Lee Jong-ho's presentation skills, and I will cheer for your presentations that 'make the audience take action'!
