Dave and Luke unpack the anterior mid-cingulate cortex (AMCC), the brain region that grows when you voluntarily choose hard things, and share a simple four-step framework for training willpower and resilience.

Show Notes & Chapters

What if discipline isn't a personality trait, but a part of your brain you can physically grow? Dave and Luke dig into the neuroscience of the anterior mid-cingulate cortex (AMCC), a small brain region tied to willpower, resilience, and even longevity.

They explain why this region measurably grows when you voluntarily choose to do something hard, and shrinks when you default to comfort. The difference between chosen difficulty and difficulty that simply happens to you turns out to matter more than it seems. Then they translate the research into a simple framework you can start using today.
