Take your chances(write a summary)quick~
A man recognized as a genius in bussiness circles was invited as an honor guest to a TV interview.Everybody was eager to hear a success story from him.He,however,only said with a slight smile:"Wouldn't it be better for me to ask you for advice on a certain problem?'
Here is the problem he raised:
"people all rushed to the place where a gold mine had recently been discovered.But when they got there they found they were blocked by a river flowing across the only way to it.What would you do if you were among them?'
"Make a roundabout way,'someone suggested.
"Swim across',said another.
The genius smiled without a word.Then he gave his view:"Why not do something else instead of rushing to the mine?How about buying a boat to do some ferrying?'
The audience was shocked.He explained calmly:"The man could make a great amount of money from the passagers.They would have been willing to pay for the ferry because there was gold on the other bank.'
Do what others have not thought to do or something never attempted before-that is the key to success.A difficult circumstance,in the eyes of a wise man,often means a potential chance for success.
