“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.
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. 小题1:Is life a long journey according to the passage? 小题2: Why do you need to set your life goal? 小题3:What should you consider when you set a family goal? 小题4:How can we achieve the main goal easily? 小题5:What does the writer want to tell us? |
