Always amazed by how the creativity in some people transforms into.

[Camus @newstart_2024]

The one brain structure that literally grows when you do things you HATE doing — and shrinks the moment you get comfortable.

Stanford neuroscientist Andrew Huberman dropped what he calls “one of the most important discoveries in the history of neuroscience” in a conversation with David Goggins.

It’s called the anterior mid-cingulate cortex (aMCC).

Recent human studies (not mice) show:
- It’s smaller in people with obesity → grows when they successfully diet
- Super-athletes have an unusually large aMCC
- People who live the longest keep this area big their entire life
- It enlarges every single time you force yourself to do something you genuinely do NOT want to do
- It shrinks almost immediately if you stop or if the same task becomes enjoyable

Huberman: “This isn’t the seat of intelligence or memory. This might actually be the seat of the WILL TO LIVE.”

The rule is brutal but simple:
If you love your ice bath → no growth
If you’re terrified of cold water but get in anyway → aMCC gets bigger
Skip a day or start liking it → it shrinks again tomorrow

Huberman waited years to tell David Goggins about this because Goggins has been unconsciously training his aMCC harder than almost anyone alive.

Watch the full clip below — it will permanently change how you think about discomfort, willpower, and longevity.

What’s one thing you really don’t want to do today… that you’re going to do anyway?

Drop it in the comments. Let’s build that aMCC together.

We worked w/ Bonobos when they were acquired by Walmart & out of 1k "never buying from you again" comments on FB and IG, only 2 were from actual customers. I think about this a lot.
