The most important lesson I learned in college was necessity of planning for my life. In Japan, around one year before college student's graduation, they start a job hunting almost all at once . Some my friends spent their time studying qualifications to be requited for the companies where they want to work. Some my friends tried to make connections and valuable experience to be desired for popular companies in Japan. However, I didn't spend my time for preparing for my job hunting, because adults around me encouraged me to just have fun in college days because people cannot have fun time after staring working. I just believed the stories without deeply thinking. As a result, I could not pass the entry exams for the companies where I wanted to work. Looking back the time, I just interpreted the adult's story for my own convenience. Through the experience, I learned that the planning on my life is very important.
