Mental models are tools for your brain. These tools are going to help you to think and make decisions clearly.
In this book, you are going to learn decision making mental models like the two-list system, where you can figure out what are the things you really want, and what are you just thinking about, but never going to do.
You will also learn the inversion model where you can solve any problem and reach any goals by completely inverting them.
You will learn 10 more mental models in this book that are going to help you become a better thinker in general.
The models described here, although nothing new, are fun to learn and very much applicable to our life's situations (whatever that might be). They are brief and so makes it easy to digest. I would recommend it to any novice who are new to the mental model game.
