20.阅读下面短文，从短文后各题所给的四个选项（A 、B、 C 和D）中，选出最佳选项，并在答题卡上将该项涂黑。

　　Stop wasting your time thinking of reasons for your failures.  Instead, realize that the seeds of success were planted within you when you were born. Only you have the power to make those seeds grow.

　　The seeds, and the power to grow them, are contained in the most awesome machine ever created: the human mind. Success is a choice and not a chance. You were born a winner. You were born rich. You can be a success if only you make the right choice.

　　You cannot be successful without first developing your self-confidence. Your level of self-confidence is always based on the degree of control that you are able to exercise over yourself, and thus over your life. People with low self-confidence are people who do not believe that they have any power, or responsibility for their lives. They are always victims. They are leaves tossed (摇摆) by the winds of chance blown about with any sudden change in the weather.

　　You can exercise control over your life only to the degree that you believe you are responsible for everything that happens in your life.  Failures think that everything happens by accident and chance. Successful people realize that they are responsible.

　　Everything happens as a result of something.  If we can identify(确定) the cause, we can control the effect. We are responsible for what we choose to think and believe. One generally rises to the level that one expects. We are responsible for setting our expectations. Our success is dependent upon our level of confidence.

　　In all areas of your life, whether they are financial, physical, or spiritual, you are responsible. Once you recognize this, accept it, and firmly believe it. You are on the road to success.
