You Are What You Eat

In applied AI, the single biggest determinant of output quality is not the model. It is the context.

The quality, adequacy, and richness of what you feed alongside your instructions is what separates a generic-sounding email from precise communication in your voice. It is what separates a strategy document that misses the mark from one informed by every relevant parameter. More high-signal context, better output.

The thing is, this is no less true for humans.

Your ability to perform well in any situation is directly tied to the context you carry into it. General knowledge. Similar situations you have been in before. How much you know about the people, the problem, the stakes.

Think about the difference between walking into a meeting cold and walking into one where you have read every document, talked to every stakeholder, and thought through every angle. Same brain. Same skills. Completely different output.

The same is true for energy. How you carry yourself, how you appear to other people: all of it is shaped by your environment.

The content you consume. The music you listen to. The people you talk to every day. The problems you choose to spend your time on. The broader culture you operate in. All of it feeds into the state you bring to your life and work. Surround yourself with high-agency people and your baseline rises. Sit long enough in a low-energy environment and it quietly pulls yours down.

Worst of all, you do not notice the drift in real time. A language model does not know when it is working with bad context. It just produces worse outputs and has no idea why. You work the same way. Spend enough time in a culture where the default is slow, cautious, and permission-seeking, and you start to believe that is normal. Your outputs degrade. Not because you lost ability, but because your context changed.

“You are the average of the five people you spend the most time with.” “You are what you eat.” People treat these like motivational posters. They are not. They are concise descriptions of how context works for humans. And the applied AI age gives us a technical framework that demonstrates, measurably, that the same engine with different context produces wildly different results.

You are the engine. Your environment, your relationships, your daily inputs: that is your context.

So curate it deliberately. Seek out people with taste, energy, and high standards. Feed your mind with context that raises the bar. Put yourself in rooms with exceptional signal. The old wisdom was always right. Now we can see exactly why.
