阅读下面短文并回答问题。(请注意问题后的字数要求)。

     [1]Everyone has dreams. Usually they obey the rule that if you can dream it, you can achieve it!If you

want to obtain a perfect life in the future, there are always some goals.

     [2]The first goal common to all of us is health and energy. We all want to be healthy and fit, to have

high levels of energy and to live free of pain and illness. Today, with the incredible advance in medical

science, the quality of our health and fitness, and our lifespan is largely determined by design, not by

chance. People with excellent health habits are far healthier, have more energy, and live longer and

better than people who have poor health habits. Remember that health is not everything, but without

health everything is nothing!

     [3]The second goal that we all have in common is to enjoy excellent relationships-personal or

social-with  the people we like and respect, and who in turn. Fully 85% of your happiness will be

determined by the quality of your relationships at each stage, and in each area of your life. How well

you get along with people, and how much they like and respect you, have more impact on the quality

of your life than perhaps any other factor.

     [4]The third common goal is to do work that we enjoy, to do it well, and to be well paid for it. You

want to be able to get and keep the job you want, to get paid more and promoted faster. You want to

earn the very most that is possible for you at each stage of your career, no matter what you are engaged

in.

     [5]The fourth goal we all have in common is to achieve financial independence. You want to reach the

point in life where you have enough money so that you never have any financial worries. You want to

be completely free of them. You want to be able to order dinner in a restaurant without referring to the

price listings to determine what you want to eat.
