A story that has a moral lesson. A lesson that should be known by everyone.
Make sure that there is a good lesson that can educate people. For example, a story of a poor child that is always bullied by everyone because of his clothes etc, then that's the thing he will use to reach his goals.
Then when the child had reached his goals like being wealthy and healthy the bullies wants to become friend with him and the child accepted it but with favor, don't bully everyone or someone. Then they became friends and that bullies became friendly.
Moral lesson : Don't judge people about their looks. The thing is to become friend with them if you think it is right.
Just like, Don't judge the book by its cover.
