John and Bobby joined a wholesale company together just after graduation from college the same year. Both worked very hard. After several years, however, the boss promoted Bobby to the position of manager but John remained an ordinary employee. John could not take it any more, tendered his resignation to the boss and complained the boss did not know how to delegate and did not value hard-working staff, but only promoted those who flattered him.
The boss knew that John worked very hard for the years. He thought a moment and said, “Thank you for your criticism, but I have a request. I hope you will do one more thing for our company before you leave. Perhaps you will change your decision and take back your resignation.”
John agreed. The boss asked him to go and 
find out anyone selling watermelon in the market. John went and returned soon. He said he had found out a man selling watermelon. The boss asked how much per kg. John shook his head and went back to the market to ask and returned to inform the boss $1.2 per kg.
Boss told John to wait a second, and he called Bobby to come to his office. He asked Bobby to go and find anyone selling watermelon in the market. Bobby went, returned and said, “Boss, only one person selling watermelon. $1.2 per kg, $10 for 10kg, he has inventory (清单) of 340 melons. On the table 58 melons, bought from the South two days ago, they are fresh and red, good quality.”
John was very impressed and realized the difference between himself and Bobby. He decided not to resign but to learn from Bobby.
Chances exist in
the daily details. For the same matter, a more successful person sees more and farther so that he can find out an opportunity and catch it to realize his aim. If a person sees one year ahead, while another sees only tomorrow. Then the difference between a year and a day is 365 times!
