Life’s a long, long journey(旅程)” so we are told, and most of us would not set off on a journey, even a short one, without some idea of where we wanted to go. Yet many people travel on life’s journey with no sense of direction at all.
Setting personal goals can give your life a sense of direction. Goal setting is used by top sports players, successful business people and achievers in all fields. Before you set personal goals, think about what you want to achieve with your life.
Try to set goals in some of the following categories (类别).
Education—Will you achieve the educational goals after finishing high-school? Are you still growing and learning
Family—What kind of relationship do you want with your parents and other family members?
Creative—Do you want to achieve any artistic goals?
Career— What job do you want to take when you grow up? What do you need to make your dream come true?
Public Service—Do you want to make the world a better place?
Physical—Are you fit enough to do the things you want to do?
Pleasure—How do you want to enjoy yourself?
To help make the process (过程) more manageable, divide your goals into smaller tasks. For example, if you want to reach a main goal in five years, set a three-year goal, a one-year goal, a three-month goal and a one-month goal. Then create a daily To-Do List of things that you should do today. When a goal is achieved, take the time to enjoy your success. This helps you build the self-confidence.
Remember, your goals can change as time goes on. But be sure your goals are things you hope to achieve, not what your parents, family or teachers want.
