One of my new personal favorites!

We can’t own a complete understanding of reality as it is. We only have a filtered and interpreted mental representation that we are mostly not aware of. The world is far to big and complex to hold everything as it is, but we view it through a set of different lenses that, each will provide a piece of information to enhance the picture of the world that we see.

Each mental model provides a tool to form a new point of view from which we can take better decisions or have a better understanding of a problem. Too many important and famous figures have applied certain mental models to achieve great actions.
