A boy who grew up in an orphanage often asked the dean pessimistically: What's the point of living as an unwanted child like me? The dean always smiles but doesn't answer.

One day, the dean handed the boy a stone and said: Tomorrow morning, you take this stone to the market to sell, but it's not a "real sale". Remember, no matter how much money others pay, you must never sell it.

The next day, the boy crouched in the corner of the market, and unexpectedly many people wanted to buy the stone from him, and the price was getting higher and higher. Back in the courtyard, the boy excitedly reported to the dean, who smiled and asked him to take it to the gold market tomorrow. Someone paid ten times more for the stone than yesterday.

Finally, the dean told the boy to take the stone to the gem market for display. As a result, the value of the stone rose ten times more than yesterday, and it was spread as a rare treasure because the boy didn't sell it at all.

The boy excitedly returned to the orphanage with the stone and told the dean all this. The dean looked at the boy and said slowly, the value of life is just like this stone. As long as you value yourself and cherish yourself, life is meaningful and valuable.
