Thank you for your review. I feel rewarded that the lecture was helpful. I agree 200 percent (or more) with what you said, "UX is not about learning a certain correct answer." As mentioned in the lecture, even if you have 10 years or more of experience in UX and UI design, I don't think that experience itself guarantees that you can create a good product. What's more important is that designers have a mindset that puts their ego aside and focuses on learning with the user at the center. As I gain more experience, I think I'm putting aside my thoughts about whether I'm right when planning and designing until I verify my hypothesis, and I'm placing more importance on studying users^^
