Choosing Your Inputs Carefully

You are, to a degree most people never appreciate, made of what you consume. Not just the food you eat, but the information you take in, the media you watch, the conversations you have, the ideas you let into your mind each day. These inputs shape your thoughts, your moods, your sense of what is normal and possible, far more powerfully than you realise. And most of us choose them carelessly, letting in whatever happens to arrive, then wondering why we feel the way we feel. Choosing your inputs carefully is one of the quietest and most consequential disciplines there is.

The mind eats too

We accept without argument that the body is shaped by what it consumes — that a diet of junk produces a certain kind of health, and a diet of good food another. Yet we rarely apply the same logic to the mind, which is also, constantly, eating. Every article, every feed, every video, every conversation is a meal for the mind, and the mind is built from these meals exactly as the body is built from its food.

A mind fed a steady diet of outrage becomes an outraged mind. A mind fed anxiety becomes anxious. A mind fed comparison becomes discontented. This is not weakness or a lack of character; it is simply how minds work. What you repeatedly take in, you become. The inputs are not passing through you without a trace. They are constructing you.

The default diet is poor

Here is the problem: the default informational diet, the one you get by simply consuming whatever the modern world pushes at you, is engineered not for your wellbeing but for your attention. The systems delivering most of our inputs are optimised to capture and hold us, and the surest ways to do that are outrage, fear, envy, and endless stimulation. Left to the default, you will be fed precisely the inputs most likely to leave you agitated, because agitation is engaging.

You would not let a stranger choose everything you eat. Yet most of us let algorithms choose everything our minds consume, and then wonder why we feel unwell.

So carelessness here is not neutral. To not choose your inputs is to have them chosen for you, by systems that do not have your flourishing as their goal. The passive consumer is not free of a diet; they are simply on a diet designed by someone else, for someone else's benefit. Choosing carefully is how you take that power back.

Curating the inputs

I have become deliberate about what I let in. I ask of my regular inputs a simple question: how do I feel after consuming this? Some sources leave me thoughtful, calmer, more curious, more generous. Others leave me agitated, envious, scattered, worse. The feeling afterward is the truest measure of an input's effect, and I have learned to trust it and to prune accordingly.

This does not mean consuming only comfortable things or hiding from difficulty. Some of the most valuable inputs are challenging, even uncomfortable — they stretch me, correct me, make me think. The distinction is not comfortable versus uncomfortable. It is nourishing versus depleting. A hard book that leaves me wiser is nourishing. A stream of outrage that leaves me agitated and no wiser is depleting, however compelling it felt in the moment.

The company you keep

The most powerful inputs of all are people. The conversations you have and the company you keep shape you more than any media, because people transmit not just information but ways of being. Spend time around the anxious and you absorb anxiety; spend time around the generous and you become more generous. We become, over time, the average of those we are most often with, and this is worth choosing with care.

I try to spend time with people who make me better — who are curious, kind, honest, alive. Not because I am using them, but because I have come to understand that the people around me are among the most important inputs of my life, and that a life is quietly steered by the company that fills it. Choosing that company well is choosing who you will slowly become.

Guarding the gate

You cannot control everything that reaches you, and I am not suggesting a paranoid vigilance over every stray input. But you can control the steady diet — the sources you return to daily, the feeds you keep, the company you seek. Those repeated inputs are what shape you, and those you can choose. The occasional input matters little; the daily one matters enormously.

So guard the gate of your mind at least as carefully as you guard the door of your body. What you let in, day after day, is what you will become. Choose it as though your inner life depended on it, because, quietly and completely, it does. I write more about attention and the shape of a life in my other essays.
