How does “knowing too much” benefit or harm you?

[deucher]

As a child, my parents always told me that if I know too much, I won't be able to sleep peacefully. Then I just took it for granted because my parents said so, but as I grew older, I wondered if it was really so and it turned out to be false for me. Because, on the contrary, I would like to know much more in order to be more educated and with this I can make an impression on people. I think you will even start thinking more clearly if you have a lot of information

Ignorance is a bliss, knowing too much will harm you. When you know too much and when you cannot have them, it will make you feel miserable.
