Because of my parents’ job, I went to different elementary schools including the one in Indonesia, which have made me interested in working abroad. After attending a private junior and senior high school in Japan, I major in economics at my home university. Considering that we must deal with various global issues, I felt it necessary to learn and understand the sustainable mindset, which motivated me to take this course. By the end of this course, I would like to master the ways to think sustainably and the ways to apply them to reality.
