I really enjoyed listening to Younghan's lectures. I am preparing to become a server developer through self-study after quitting my job as a non-major, and I think I learned the most when I listened to Younghan's lectures. He simply explains only the necessary parts and focuses on source code, so I can listen without getting bored, and I think I can understand and remember things well. I will listen to the remaining lectures on the roadmap well. Thank you for the great lecture.
