Physical sensations like tension or ease contain information your conscious mind may miss.
Things that feel urgent are rarely the most important — urgency is a noise amplifier.
Curating better inputs is more efficient than filtering bad ones. Every hour spent choosing credible sources saves ten hours of downstream fact-checking, second-guessing, and correcting decisions built on noise.
Every minute spent consuming noise is a minute stolen from depth. The cost of staying informed about everything is understanding nothing well enough to act on it.
Strong emotional responses to information often indicate manipulation, not importance. Your triggers are not a relevance filter — they are a vulnerability map.
The metrics that predict your future are different from the metrics that describe your past. Most people track the wrong ones — and by the time they notice, the future has already arrived.
Experts do not process more information than novices. They process less — because they have learned which information to ignore. Expertise is not faster consumption. It is superior filtration.
When you cannot distinguish signal from noise, the highest-value action is usually inaction. Time is a filter — it degrades noise and amplifies signal. Forcing a decision under ambiguity does not resolve uncertainty; it converts uncertainty into error.
Recording what you expect to happen and comparing to what actually happens is the only reliable method for calibrating judgment. Without a written record, hindsight bias rewrites your memory of what you believed, making genuine learning from experience impossible.
Your emotions do not add random noise to perception — they warp it in predictable, measurable directions. Anxiety inflates threats. Euphoria shrinks risks. Anger manufactures certainty. Once you know the direction of the distortion, you can correct for it.
Insufficient sleep impairs perception as much as moderate alcohol intoxication — and unlike alcohol, you cannot feel it happening.
Under stress your perceptual field contracts — you see less, process less, and mistake the narrow slice you do perceive for the whole picture. Recognizing this contraction is the first step to correcting it.
Basic physiological states measurably alter what you perceive and how you evaluate it.
Recent events disproportionately influence your perception of what is normal or likely.
Imagining failure in advance corrects for optimistic perception biases.
Update the strength of your beliefs proportionally to the strength of new evidence.
The ability to see clearly — not optimistically, not pessimistically, but accurately — is rarer and more valuable than most technical skills. Calibrated perception compounds into better decisions, and better decisions compound into better outcomes at every timescale.
Information has no inherent meaning. Meaning is constructed at the intersection of information and context. Change the context, and the same data, sentence, or signal means something entirely different.
Before interpreting any information, identify the relevant context. The same data, the same words, the same event will mean completely different things depending on where you are, who you are with, what you are trying to accomplish, and what just happened. If you do not ask "what context am I in?" before you interpret, you are letting your default context — the one your brain loaded automatically — do the interpreting for you. That default is often wrong.
Understanding how you got here prevents you from making the same errors again.
When evaluating past decisions reconstruct the context that existed at the time.
Assumptions you never write down are assumptions you never question. Every plan, decision, and belief rests on invisible premises — and the invisible ones are the ones that destroy you.
If you cannot point to a written list you do not have priorities you have reactions.
Operating on a flawed schema produces systematically flawed decisions.
Classifying items by importance or urgency enables systematic decision-making.
Putting something in the wrong category means the wrong actions get applied to it.
Going deep in one branch versus wide across many branches are different strategies with different costs — and the right choice depends on whether you need resolution or coverage.
Refusing to update schemas means making increasingly poor decisions over time. Rigid schemas do not merely fail to improve — they actively degrade your judgment, because the world changes while your models do not. Every day you operate on an outdated schema is a day your decisions drift further from reality. The cost is not a one-time penalty. It compounds.
When two schemas contradict you need a meta-schema for deciding which to trust.
You need rules for choosing which schema to apply in a given situation.
Your risk model determines what you attempt and what you avoid.
Direct results and other peoples reactions are both valuable but different types of feedback.
Execution errors knowledge errors and judgment errors require different correction approaches.
Design systems that surface errors early when they are easiest and cheapest to correct.
When agents conflict the higher-priority agent wins.
When two agents each wait for the other neither can proceed — design to prevent this.
A well-written document delegates explanation, alignment, and decision context to the future.
A rule is a pre-committed decision that prevents you from having to re-decide the same thing every time.
Delegation ranges from "do exactly this" to "handle it entirely" — know which level you are using.
Monitoring without action is observation theater — data must drive decisions.
Each improvement gets harder and smaller — know when further optimization is not worth the cost.
The optimal amount of optimization is not infinite — there is a point where you should stop and move on.
Run two versions of an agent simultaneously and let the data tell you which performs better.
Record what you changed, why, and what happened — optimization without documentation is gambling.
Optimizing before you understand the system is the root of much wasted effort.
Sometimes you should improve an existing agent; sometimes you should replace it entirely.
Others can influence your thinking — and should — but influence is an input, not a command. Authority over the final judgment remains yours.
