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.   小题1:  

Be responsible for yourself

Sometimes you may want to blame others for your failure to get ahead.   小题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. 小题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

  小题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.

  小题5:  

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.In fact, when you say someone or something outside of yourself is stopping you from making success, you’re giving away your own power.

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

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

D.Here are some keys to success that they give.E. Make a decision

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

G. Don’t delay
