When asked to free write about what is happiness, I initially thinks more individually, which are family, healthy, feeling, and personal activities. However, it change my intension about happiness after we read the book “Happy City” and had the conversation about happiness. I learned that what happiness means to the people who live in urban cities. Experiences and connections might be the main concerns to create happiness for people. Just because people will no longer live alone in urban cities. People meet others everyday and everywhere.  So how to absorb these critical principles into urban design to make a better neighborhood, including blocks, streets, parks, interactive space, will be the responsibilities for designers.
