maintain the pathways in your brain that let you learn and create new memories, and it’s harder to concentrate and respond quickly.

Sleep is crucial to overall health and daily functioning

“Scientists have learned that animals that experience prolonged stress have less activity in the parts of their brain that handle higher-order tasks—for example, the prefrontal cortex—and more activity in the primitive parts of their brain that are focused on survival, such as the amygdala. It’s much like what would happen if you exercised one part of your body and not another. The part that was activated more often would become stronger, and the part that got less attention would get weaker. This is what appears to happen in the brain when it is under continuous stress: it essentially builds up the part of the brain designed to handle threats, and the part of the brain tasked with more complex thought takes a back seat.”9
With such clear evidence that stress can be debilitating to your brain, finding ways to reduce or avoid stress becomes critical.

Every time you answer a question and do a new activity, you rewire your brain.

Someone who is constantly asking themselves how to get people to like them can never truly be their true self because they will always be molding themselves to the preferences of the people around them, even if they’re not aware of it. You know all this information, and you only know one question they ask themselves. What do you think is your dominant question?

When we write something down, we’re more likely to do what we promise.

How motivated, energized, and focused are you at this moment? Rate your current state on a scale of 1 to 10. What is one thing you will do right now to increase that number?

remember names with my method, which I’ll teach you later in this book

Pomodoro technique, a productivity method developed by Francesco Cirillo based on the idea that the optimal time for a task is 25 minutes, followed by a 5-minute break.2 Each 25-minute chunk is called a “Pomodoro.” As you read this book, I suggest that you read for one Pomodoro and then take a 5-minute brain break before continuing.
