Routine can help structure a person's life, but too much can cause life to slip away, which can lead to regret. No routine and only being spontaneous can lead to a life of wandering around without any purpose. Both sides are extreme, and you need a balance. I discovered this when college started in Taiwan. The first week of trying to figure out where my classes were, and my schedule was stressful.
In Taiwan, students are given a week to create their schedules, this means attending classes they would like to join or dropping ones that do not fit. The first class I attended was a master's class in English on Confucianism. I thought it would be perfect, a culture class that would fulfill my second major's requirements, and it was in English. Perfect! My classmate from NAU, who was in the same program as me, attended the class with me. As soon as the professor came in, he announced that the course was, in fact, not taught in English but encouraged us to sit in on the first lesson. I can barely understand the principles of Confucianism in English, much less in Chinese. I sat there for two hours, wondering what in the world I was getting myself into. I could cross that class off my list.
Eventually, my schedule was two online classes at NAU, Chinese movies and culture (completely in Chinese), children's literature (completely in Chinese), a speaking and listening Chinese language class, and another Chinese language class that was five days a week. My routine and new life in Taiwan were coming together.
