                                                        The Winner's Guide to Success

      How do successful people think? What helps them to make success? To find out the

answers, an American scholar recently visited some of the most successful people in

America.   1  

     Be responsible for yourself

     Sometimes you may want to blame others for your failure to get ahead.    2     You're

saying, "You have more control over my life than I do."

     Live life "on purpose"

     Almost all successful people live life "on purpose"- they are doing what they believe they

should and want to do. When you live your life on purpose, you'll try your best to do your

job or study as well as you can. You love what you do and you can find pleasure in what

you do.

     Write a plan

     It is very difficult trying to get what you want without a good plan.     3     A good plan

is like a map to you. Without this "map", you may waste your time, money and also your

energy; while with the "map" you'll enjoy the "trip" and get what you want in the shortest

possible time.

     Be willing to pay the price

     Nothing great is easy to get. So you must be ready to work hard - even harder than you

have ever done. If you are not willing to pay the price, you won't get anything valuable.

     Never give up

        4   When you are doing something, you must tell yourself again and again: Giving up is

worse than failure because failure can be the mother of success, but giving up means the death

of hope.

     Once an American writer was writing a novel. He could not have a good ending for his

book until one night when he had a very good idea. He was so excited that he made a phone

call to one of his best friends. "I've got a perfect idea," he said, "I'll put it down later and show

it to you." But he never did, because he died that night. His book was left without a perfect

ending. So remember, do what you can right away. Never delay at all.  

A. It is just like trying to drive through strange roads to a city far away.

B. It seems to us that everyone knows this. But it is easier said than done.

C. Some people achieve success much later in life because they fail to realize earlier the importance

     of hard work.

D. In fact, when you say someone or something outside of yourself is stopping you from making

     success, you're giving away your own power.

E. Someone else's opinion of you doesn't have to become your reality.

F. Don't delay

G. Here are some keys to success that they give.
