I've recently read an article in which the author mentioned a story. There was an elephant trainer, who kept his elephants captive by only a thin string. A curious man asked him, howcome the creatures don't simply tear the string and escape. The trainer answered that young baby elephants are tied up with the same string. When they're young, the string is strong enough to withstand their attempts to tear it apart. They slowly accept that they cannot tear the string. By the time they grow big they have already internalised their beliefs and never again question them.

Have you ever asked yourself, which of your beliefs are only a thin string?
