In the book Mindset, Dr. Carol Dweck shows the importance of a growth mindset rather than a fixed mindset. Why is a growth mindset essential for UX designers? As a UX designer, you should be bold enough to admit things you don't know and believe you can find the proper solution for the problem you are working at. In another way, the UX discovery stage for designers is a trial-and-fail process, which requires a growth mindset so you can reflect on what you've learned and adapted it to your design.
