     What does it mean to relax? Despite hearing this term thousands of times during the course of our lives,

very few people have deeply considered what it's really about.

     When you ask people what it means to relax, most will answer in a way that suggests that relaxing is

something you plan to do later-you do it on vacation, when you retire, or when you get everything done. This

means, of course, that most other times (the other 95 percent of your life) should be spent nervous, restless,

rushed, and mad. Could this explain why so many of us perform as if life were one great big emergency

(紧急事件)? Most of us put off relaxation until our " in-basket (收文篮)" is empty. Of course it never is.

     It is useful to think of relaxation as a quality of heart that you can own on a regular basis rather than

something left for some later time. You can relax now. It's helpful to remember that relaxed people can still be

super achievers and, in fact, that relaxation and creativity go hand in hand. When I'm feeling upright, for

example, I don't even try to write. But when I feel relaxed, my writing flows quickly and easily.

     Being more relaxed includes training yourself to react differently to the dramas (戏剧) of life-turning your

melodrama (情节剧) into a sweet-drama. It comes, in part, from reminding yourself over and over again

(with loving kindness and patience) that you have a choice in how you respond to life. You can learn to relate

to your thinking as well as your situation in new ways. With practice, making these choices will translate into

a more relaxed self.

3. According to the passage most people think of relaxation as _____.

A. something planned to do in the future

B. something to be done now
