Liao Chaidian, president of the American International Investment Consulting Company, has a percentage law: if you meet 10 customers and only get an order of 200 yuan at the 10th customer, what do you think of the first nine failures and rejections? He said, the reason why you got an order of 200 yuan is because you met with 10 customers. It is not the 10th customer who gave you 200 yuan. Instead, it should be regarded as that every customer let you do a business of 200 yuan / 10 yuan and 20 yuan. Therefore, the income rejected each time is 20 yuan. When you are rejected, when you think that this customer has rejected me, it means that I have earned 20 yuan. You should also smile and salute as earning 20 yuan.
