This was a lecture I listened to because I wanted to understand and use the principles and concepts properly after experiencing Spring several times. It was a lecture that made me understand why everyone around me was calling me Younghannim Younghannim. You scratched all the itchy parts. I will listen to the remaining lectures diligently. Thank you.
