I'm leaving a review after listening to half of it. I've always wanted to study development, but whether through books or anything else, I had a hard time getting over the threshold because I didn't have a basic and overall understanding of the environment. This lecture helped me get over that threshold. I think I learned how to take each step. I still stumble a lot, but if I don't slack off on my studies, I think I'll soon become a sprinter. ㅎㅎ I have to work harder because I'm so grateful. Thank you~!
