I liked how he spoke so clearly, and I thought it was a really good lecture to learn the basics. I have purchased and am studying all of Kim Young-han's lectures. I am so grateful that he prepared such great lectures, and I am grateful once again for being able to learn so much! I have seen Young-han in the media many times before, but I think the lecture that I remember the most is "One day, a junior developer with many worries came to visit." I will continue to study hard with good lectures, grow, and take the next step.
