I've already been through YouTube once :) In fact, people who find it fun while studying IT probably had a big dream of Silicon Valley at least once. However, due to lack of information and the daunting reality, they seem to have given up on their dreams or naturally forgotten them. Through this challenge, I was able to face the concrete reality and have a bigger dream in my heart. As much as the teacher gained confidence in what he taught himself, I, the listener, also gained confidence and pride in what I am learning from the teacher. I will continue to work hard. Thank you always!
