Saw this story online. I shortened it to its essentials:
A tortoise family decided to go on a picnic. Being slow, they took two years to find an ideal spot. Then, they realised they forgot the salt. After a long discussion, the fastest tortoise was chosen to get it from home. He agreed to go if they would wait for his return before starting the picnic. The others agreed. Seven years went by and he did not return. One of the tortoise decided to start eating. Suddenly, the missing tortoise popped out from behind a rock and yelled, ‘I knew you wouldn’t wait! That’s why I’m not getting the salt!’
This is the moral that came with it:
Some of us waste our time waiting for people to live up to our expectations. We are so concerned about what others are doing that we do not do anything ourselves.
Here is another one I came up with:
If we cling to our false beliefs strongly, we might gradually force these self-fulfulling prophecies to manifest ‘truths’. Beware of what you believe!
