Long long ago when subcontinent was a very civilized and a bloody wealthy area on the planet in money and knowledge, there was a great guru of all times who knew everything in the world. It was the dream of every parent, and every kid to become a student of this guru. But the guru was very selective. Most kids and parents respected his selectiveness and never asked him why if the guru decided not to choose a kid as his student. One day a kid of about 7 years approached the guru, paid his respects to him, and asked him if he can join the guru's 'Gurukul' as a student and learn from him all that the guru teaches his other students. The guru, who has never had to explain to anyone about his selection process so far, thought for a moment, and told the kid that he would like to give the kid a series of tests, and the kid agreed. The guru gave the kid a big sparkling stone the size of his palm, and asked him to take it to a bunch of kids playing at the river banks and offer to trade it for something else and find out what he would get. He was to bring the stone back, never to trade it or sell it, only to assess the value of the stone and what he would get in return for it. So the kid took the stone to the other kids playing in the river bank nearby, outside the gurukul, and showed them the stone. The other kids looked at it, and wondered what they could do with it. For them it was just another stone that they could toss into the river and play with, and so they said it was worth nothing to them as they had plenty of stones lying around already, and they could do with less shinier stones too. The kid came back to the guru and told him this. Then the guru asked the kid to take it to a grocery market and find out the value for the stone there. The traders there found the sparkling stone attractive, but they didn't find the stone to be of any use to them, except perhaps to be used as a weight for their scales, so offered 10 times the weight of the stone in groceries in exchange. The kid came back and said this to the guru. The guru then asked the kid to take the stone to a jewelry store, and the jeweler's eyes gleamed at the sight of it and he said "Holy Fuck thats a fuckin large diamond, you can never find one that size." He offered 100 bags of gold for it (1 bag of gold in ancient times were 100 x 1 gram coins, thats 10 Kg of gold). The kid came back to the guru and told him this. Now the guru said to the kid, "What I teach you is like the stone in your hand, and you are still one of the kids playing on the riverside. You don't know its value and you would only look at it like another stone that you could toss into the river. For that you could do with a less sparkly stone too, and you would get the same amount of fun. Even if you find the knowledge valuable as time goes by, you will only use it as a weight for your scales just to benchmark the shit you sell. To make real use of the knowledge I give you, you will have to become that jeweler who truly understands the real worth, and would put the knowledge to great use, and make sparkling pieces of jewelry out of it. If I take you in as a student now, you might only feel the pride of playing with a sparkling stone, but what I teach you would be of no real use to you as in the end, you are only going to toss it into the river, and it would be a bloody waste of time for me which I might rather spend teaching someone who would make sparkling pieces of work with the knowledge I give him. And thats why I handpick only the worthy. So make yourself more worthy, and come back to me, and I'll teach you all that I know."
