There is a rumor in the world. This rumor is very deep and only a few people know it. This rumor is that there is a black diary in the world.
Whatever you write down, you will forget about it the next day, but it will take away your worries.
Another version is that no one who writes a diary in a black notebook can live past the age of 60. After writing the most important point, it will disappear the next day and no one will remember having this notebook.
Intention: Be happy
