Going overseas and living alone in foreign country offer a great experience and opportunity for self-development. Self-development means taking personal responsibility to develop a good behaviour, self control, and also the way of think. As students meet many new people and adjust ourselves to different custom, their way of think will be changed. By sharing stories and experiences with new friends about life and culture, or sharing opinion to solve problem in study case inside the class, students will learn and see different point of views. They become open-minded. Self-control and responsibility are learnt by living far away from family. It teaches them to rely on nobody but themselves. Thus, it will motivate themselves to be more independent, responsible and confident in taking a decision. A good self-control will lead students to a success of achievement. For instance, many students experience failure of study because of losing self control by hanging out too much with friends so they cannot manage time for studying. Self development will bring them to have better personal skills that are required in workplace later.
