I was ten when I first sat with my grandmother behind the cashier(收银台)in her general store． 1 I quickly learned the importance of treating customers politely and saying “thank you．”
At first I was paid in candy． 2 I worked every day after school, and during the summer holidays and on weekends from 8 a. m. to 7 p. m．My father helped me set up a bank account． 3
By the time I was 12, my grandmother thought I had done such a good job that she promoted me to selling cosmetics(化妆品)．I developed the ability to look customers directly in the eye．Even though I was just a kid, women would ask me such things as “What color do you think I should wear?” I took a real interest in their questions and was able to translate what they wanted into makeup(化妆)ideas． 4
The job taught me a valuable lesson：to be a successful salesperson, you didn’t need to be a rocket scientist－you needed to be a great listener． 5 They are no longer women buying cosmetics from me; instead, they are kids who tell me which toys they would like to see designed and developed．
A．Later I received 50 cents an hour．
B．Before long, she let me sit there by myself．
C．As a result, I sold a record amount of cosmetics．
D．Today I still carry that lesson with me：I listen to customers．
E．My grandma’s trust taught me how to handle responsibility．
F．Soon I found myself looking more beautiful than ever before．
G．Watching my money grow was happier than anything I could have bought．
