From my mother, an elementary school librarian, from Sesame Street to my childhood, much of my literary development was affected and happened to my first glasses. I can look back and say, "That moment changed my life." This is a definitive moment's story that changed the way I read and write. I learned this from a whale. This is the beginning of my seventh grade. I am about 12 years old, I think you can say otaku.
In the user experience design, a decisive moment is memorable and a meaningful experience. This definition is related to the context of the scenario. A product used in a year may have a moment defined for the user. There is no definite moment and the difference with the 1 minute product. In the user experience design, our attention to the user experience becomes useless when it comes to a very small moment of each touch point of the product. These moments will function in different ways to enhance the user's mood, provide insight into the task, be proud of the task, and perhaps provide a connection with other users. See here for a more compact one page summary of this paragraph on this paragraph.
Everyone has some decisive moments in life. This is not a definitive moment but it is a reaction to your critical moment that will be a reality. One of my decisive moments was that my first manager said that I am not suitable for this industry. This encouraged me to prove to myself that I was better than I was marked. After building teams and organizations, I noticed that people showed fundamentally different performance under different leaders. Employee performance depends on individual circumstances, colleagues, and the company itself. Leaders who maximize the potential of employees can build successful teams. A leader with the correct intent will be the source of inspiration, not the source of destruction.
