In this rapidly evolving world, I was able to think about how UX design should be approached through various examples. During the 3-week challenge period, I read one small chapter each day, wrote posts weekly, and shared discussions in live sessions. One concept that particularly stood out to me was negativity bias, which I learned about early on. When I personally collected UX cases, I felt there were notably many negative ones, which can ultimately be seen as being influenced by this negativity bias. Beyond that, it was a meaningful experience to connect cases I already knew with concepts and to share discussions with other challenge participants. I had always wanted to conduct case studies, and I'd like to continue the blogging activity I started by participating in this challenge. Rather than just stopping at case collection, I now want to analyze them and think of ways to improve them. Most importantly, I'm especially reminded that what matters is completing posts so that someone can read them. It was an enjoyable challenge even amidst a busy schedule!
