My word.

One more day.

I can run through a brick wall after watching this.

Something I noticed when I visited China was public schools always started their days off with a run.

A school in Naperville, Illinois, did an experiment on this and called it "Zero Hour".

Before school, students would hit the gym at 7am and push their heart rates to 80% of their max. Then went on to do class.

The result? Reading scores doubled. Math scores jumped 20x.

On an international test, Naperville 8th graders finished 1st in science (beating Singapore) and 6th in math globally.

Some of my entrepreneur clients swear by doing cardio in the morning. They say it keeps their brain sharp. I don't disagree.

Cardio isn't just for your heart. It's brain fuel.

Exhaust the body to sharpen the mind.

The math on this project should mass-humble every AI lab on the planet.

1 cubic millimeter. One-millionth of a human brain. Harvard and Google spent 10 years mapping it. The imaging alone took 326 days. They sliced the tissue into 5,000 wafers each 30 nanometers thick, ran them through a $6 million electron microscope, then needed Google’s ML models to stitch the 3D reconstruction because no human team could process the output.

The result: 57,000 cells, 150 million synapses, 230 millimeters of blood vessels, compressed into 1.4 petabytes of raw data. For context, 1.4 petabytes is roughly 1.4 million gigabytes. From a speck smaller than a grain of rice.

Now scale that. The full human brain is one million times larger. Mapping the whole thing at this resolution would produce approximately 1.4 zettabytes of data. That’s roughly equal to all the data generated on Earth in a single year. The storage alone would cost an estimated $50 billion and require a 140-acre data center, which would make it the largest on the planet.

And they found things textbooks don’t contain. One neuron had over 5,000 connection points. Some axons had coiled themselves into tight whorls for completely unknown reasons. Pairs of cell clusters grew in mirror images of each other. Jeff Lichtman, the Harvard lead, said there’s “a chasm between what we already know and what we need to know.”

This is why the next step isn’t a human brain. It’s a mouse hippocampus, 10 cubic millimeters, over the next five years. Because even a mouse brain is 1,000x larger than what they just mapped, and the full mouse connectome is the proof of concept before anyone attempts the human one.

We’re building AI systems that loosely mimic neural networks while still unable to fully read the wiring diagram of a single cubic millimeter of the thing we’re trying to imitate. The original is 1.4 petabytes per millionth of its volume. Every AI model on Earth fits in a fraction of that.

The brain runs on 20 watts and fits in your skull. The data center required to merely describe one-millionth of it would span 140 acres.

I think it’s pretty cool that almost every municipality in Norway now has “equipment libraries” where you can borrow gear for free — like footballs, tents, skis, bikes, helmets, kayaks, hammocks, etc.

Shopify CEO Tobi Lutke: It’s impossible to make great products if you don’t give a sh*t

“Every product in the world, at the end of the day, is simply a reflection of how much the people who created it gave a sh*t… It is not possible to make great products if the people who work on it do not give a sh*t about the product.”

Tobi continues:

“I actually think this is a very important role for product leaders: To make sure that the team gives a sh*it… The product leader has to give a sh*t. Do not engage in work on a product that you don’t care about.”

Tobi believes anyone who wants to build great products has two roles:

1. “You have to understand the thing that’s being done better than everyone else.”

2. “You’ve got to be exothermically infectious with actually caring about this thing because just that one thing alone will make a 10x better product. It’s crazy how much of a change this makes.”
