DID YOU KNOW?

WE ARE ALL BORN WITH THREE BRAINS

SURVIVAL INSTINCTS

THE FIRST BRAIN

Rooted in our brain stem and cerebellum, the Reptilian Complex is our “first” brain, primarily focused on the base layer of Maslow’s Hierarchy of Needs––survival.

EMOTIONS & FEELINGS

THE SECOND BRAIN

Our second brain is the Mammalian Brain, anatomically our Limbic System, which primarily deals with our emotions. This is represented by the middle two tiers of Maslow’s Hierarchy of Needs––security (our mental health, or, our relationship with ourselves) and belonging (our social health, or, our relationship with others)

LOGIC & REASON

THE THIRD BRAIN

Our third brain is the Human Brain, our Neocortex (especially the Prefrontal Cortex), which is primarily responsible for reasoning, logic and temporal planning. It is where critical, clear thinking resides, and it is what sets us humans apart from any other animal ever.

THINK CLEARLY AND POSITIVE-SUM

Chapter 0: Growing The Pie

WHAT DOES IT MEAN TO LIVE A GOOD LIFE?

We start with meta-thinking, the most important skill of all to learn. Learning HOW to think is the most important, compounding life skill as it upgrades your default decision-making operating system.

Chapter 1: Clear Thinking

HOW TO THINK > WHAT TO THINK

HOW TO THINK > WHAT TO THINK

HOW TO THINK > WHAT TO THINK

Thinking clearly and positive-sum is about realizing the world is not so black-and-white, it is not so binary. Rather, the truth resides in the messy gray, the nuance.

Chapter 2: Personal Growth

FAIL FORWARDS FAST TOWARDS YOUR BEST SELF, REPEATEDLY

By training your mind to develop a fail forwards fast perspective, you turn all failures into learning opportunities and become anti-fragile (stronger) as a result––the obstacle is the way

Chapter 3: Objective Truth

SEEK SHARED REALITY THROUGH SOCRATIC DIALOGUE

Thinking clearly and positive-sum means realizing the world is not so black-and-white. Rather, the truth resides in the messy gray––and to find it requires consistently engaging in open dialogue with radical candor
