     The greatest saleswoman in the world today doesn't mind if you call her a girl (1) This is because Markita

Andrews made more than $ 80, 000 by selling cookies when she was 13 years old.

     Andrews and her mother shared a dream of travelling around the world. (2)Once, while reading magazines,

Andrews found that the person who sold the most cookies would win a free trip for two around the world.

She decided to have a try.

     To make her dream come true, Andrews went door to door every day after school and repeated, "Hi, I

have a dream. I'm earning a trip around the world for my mom and me by selling cookies." Then she asked,

"Would you like to buy one or two dozen boxes of cookies?"

     Andrews kept asking for a whole year, no matter how heavily it was raining or snowing outside. Her hard

work paid off. She sold 42, 000 boxes of cookies that year and she won her trip around the world.

     Andrews is no smarter than thousands of other people. The key to her success is that she has found the

secret of selling: Ask. Ask. Ask! Many people fail before they even begin because they fail to ask for what

they want.  

     It takes courage to ask for what you want. And, as Andrews has discovered, the more you ask, the easier

it gets.
