W: Hi, Jack! What is so interesting?
M: Hi, Jane. I’m thinking about a problem. You know recently I have read about a book named Setting Life Goal. I’m deeply touched by it.
W: Really? What is this book about?
M: You know Jerry White?
W: Yes, I know something about him.
M: He is so great that he always succeeds in whatever he does. Do you know why he is so successful?
W: Sorry, and why?
M: He succeeds because he has the definite life goals.
W: What is goal by your understanding then?
M: A goal is something that a person hopes to get in the future. Everyone should have a goal or goals in life if he or she hopes to lead a successful life.
W: OK, tell me in detail about what the book says.
M: Well, there are three kinds of goals;they are lifetime goals, intermediate goals and short-term goals.
W: What is a lifetime goal then?
M: A lifetime goal means the goal that a person hopes to get in all his life. It should be clear, reasonable and written out, such as the goal to become a lawyer as you are longing for, and so on.
W: I see. But what kind of goal will be the intermediate goal?
M: It relates to the outcomes during the next few years.
W: Then the third one...
M: It is a short-term goal, which involves outcomes expected during the next twelve months. This goal helps with achievement of intermediate goals.
W: Great! Goals actually are important for the different stages of our life. And now I must work out what are the life goals of mine.
