When a circus elephant is young, it is tied to a heavy wooden stake with a strong chain. No matter how hard it tries, it cannot break free. After many failed attempts, the young elephant learns that the chain is unbreakable.

As the elephant grows into a massive adult—capable of uprooting trees—it never tries to break the chain again. It remains tied to the same small stake with the same thin chain. Why? Because it believes it cannot escape. The elephant’s memory of failure has become a mental cage.

I can’t directly provide or reproduce the full text of El elefante encadenado by Jorge Bucay as a PDF, since that would violate copyright. However, I can briefly retell the story in my own words so you get the core message. (paraphrased)
