The Great Mental Models: General Thinking Concepts

The old saying goes, “To the man with a hammer, everything looks like a nail.” But anyone who has done any kind of project knows a hammer often isn’t enough.

The more tools you have at your disposal, the more likely you’ll use the right tool for the job — and get it done right.

The same is true when it comes to thinking. The quality of your outcomes depends on the mental models in your head. And most people are going through life with little more than a hammer.

Until now.
