There is no substitute for experience

A king announced, "Whoever can feed my big goat to his full stomach for a day, I will give him half of the kingdom and my daughter." 

In the hope of getting half the kingdom and the princess, people from far and wide come and take the goat in the morning. They feed it very well all day long and return it to the royal court in the evening. The king puts two grasses in front of the goat to test its appetite. 

The goat immediately eats both grasses. The king says with great regret: What, you have not fed my goat to his full stomach. It is hungry. You have failed. Everyone tried in this way and could not. No matter how much he feeds it to its full stomach, the goat goes crazy when it gets the king's grass and eats it. No one else comes to take the goat. 

The king said: There is no such person in my kingdom who can feed my goat to his full stomach. 

Can you feed it?  

A young shepherd came and said: Jahapana, I can feed your goat to the full. Keep the documents of half the kingdom and the princess ready. 

The king laughed softly: Bring the goat to the full in the evening. Many people said that. 

The shepherd came in the evening with the goat. 

The king very confidently placed two grasses in front of the goat, but the goat turned away. Despite many attempts, the goat did not take the grass in its mouth. At one stage, the king, with the help of his commander, used force to open the goat's mouth and put the grass in. 

He said: Look, the goat was hungry. It ate the grass. Everyone present in the royal court started laughing loudly. 

The king looked and saw that the goat had vomited the grasses. 

The shepherd got half the kingdom along with the princess. 

One day, the king asked: Father, did you give food to my goat? My goat was not hungry. 

Young man: Oh my God, I have gained a lot of experience in raising goats. 

King: I understand that, Father. 

Young man: I took the goat to my house and put grass and all kinds of leaves in front of its mouth. When it eats the leaves and puts its mouth on the grass, I hit the goat's ass with a cane and give it a few blows. It keeps on barking. If it puts grass in its mouth, it will spit on its ass. By eating the blades, I have created a hatred for grass. If it accidentally eats grass, it will immediately vomit. It knows that if it puts grass in its mouth, it will be beaten severely. It did not take the grass you gave it.
