What will you do to make sure you reach your goals? There are 1 main steps .

First, sit down and  2 your dreams out. By writing them you will get a better idea of where you really want to go. Imagine yourself at the end of the year or maybe 3  five years. What do you see? 4 do people see you? What are you doing? Are you  5 ?

Well, a dream is just that. It’s a vision (远见) of how you  6  yourself in the future. As long as you know the direction in which you want to go, you can begin  7  some goals.

8 come the goals. Goals are ‘wants’. So are dreams, but goals are more specific (具体的). If you want to be rich, tell how much 9 you need to be rich. If you want  10 grades, tell what you mean by ‘good’. In fact, the more specific the goal is, the  11  it will be to get it. Give numbers and times. Don’t use words like ‘lots’ or ‘more’.  12, I want a ‘B’ in each of my subjects.

Third are the objectives (目标). They tell  13  what you will do and when you will do it. When you think about what you will do, don’t use words like ‘ 14 ’ or ‘maybe’. Be sure your objectives can be measured (估量). Every day or every week you can ask, ‘Did I  15  this?’ and you can answer with either a yes or a no. Don’t leave room for ‘maybes’.
