It's a long time ago. One worker was walking through the forest with his ass. At the side of the road, he saw some brightness. When he got closer, he saw a glowing stone lying there. He picked it up and caught his ass and started to move on.
A diamond merchant saw the precious stone stuck in the neck of the donkey. Then he asked the owner of the donkey, 'Brother, I want to buy this stone. How much money will you take? ' The worker did not have any idea about the value of the stone. He said that only a hundred rupees will take it. The diamond merchant said, 'a hundred rupees are very much. I will not give more than fifty rupees. ' They said that the workers will not take less than a hundred rupees and think about it. The trader thought that he would not get a carpet for this precious stone. Then this worker will get his way back to sell the stones at Rs. 50.
After a while, the worker did not come to the merchant. Finally, the businessman went in search of him. He saw that another businessman was buying a precious stone from him. The businessman reached the laborer. Till then, the dealer left. The trader asked the worker, 'How much money did you get for the stone?' The worker said, '200 rupees'. The trader said to him, 'O fool, this stone was very valuable and you only sold for 200 rupees!' The worker answered, 'I am not a fool, you have decided. Because I had found this stone lying on the road and I did not know the price. But even though you know its price, you did not buy this stone for just Rs 50. If you had bought this stone at Rs 100 then you would have got a big advantage in the future.
