What I write about 03 categories
Category 01 - Built in public

AutoQuant, SwingTrader, LangGraph pipelines, gbrain. I build things and write about what breaks, what ships, and what I'd do differently.

AI Systems
Category 02 - Earned in the field

President's Club, Seagate close, cold email experiments, pipeline forensics. What actually works in enterprise software sales in 2026.

Enterprise Sales
Category 03 - Real capital, real rules

Bayesian signal grading, options flow, regime detection. Trading systems that learn from every trade and update their own weights.

You Are Not Lazy. You Are Governed.
Identity · Mental Toughness · July 2026

You Are Not Lazy. You Are Governed.

You have never had a motivation problem. You have a governor, a ghost, a belief-filter that closes its own loop, and an empty evidence file - and the moment you don't want to do it isn't the obstacle. It's the equipment.

The Architecture of a Personal OS
Systems · Productivity · July 2026

The Architecture of a Personal OS

You already have a daily operating system. The question is whether you designed it - or inherited it by default. The four layers that connect values to daily action, and what breaks when any one fails.

The Mechanics of Daily Execution
Productivity · Systems · July 2026

The Mechanics of Daily Execution

The gap isn't between knowing and deciding. It's between deciding and executing. Why analog beats digital, a 6-step planning system, and the six-task cap that makes every day winnable.

The Inner Game
Identity · Psychology · July 2026

The Inner Game

You can nail your task list and still feel hollow. Identity, purpose, and presence - the inner-work layer beneath every system, and why your OS only compounds when it's pointed at something real.

The Blame Market
AI · Economics · July 2026

The Blame Market

Nobody was ever paying you for the answer. They were paying you to be blameable. A model cannot be a defendant - which makes culpability the last scarce input, and rewrites what a professional is actually worth.

The Marginal Cost of a Thought
AI · Economics · July 2026

The Marginal Cost of a Thought

For 300,000 years thinking was free at the margin. Tokens gave it a unit price - and everything that gets priced then gets budgeted, arbitraged, rationed, and hedged. The failure mode isn't hallucination. It's silent under-thinking.

The Last Reality-Trained Cohort
AI · Learning · July 2026

The Last Reality-Trained Cohort

Everyone worries about models collapsing from synthetic data. Nobody is watching humans collapse from synthetic mentorship. AI took the junior's tasks - which were the substrate expertise was manufactured from.

What Saturday Knows
AI · Behavioral Economics · July 2026

What Saturday Knows

Timestamp a hundred million AI conversations and the graph starts to breathe like a life. The off-hours are the most honest focus group ever built - and they reveal what people actually want when no boss is watching.

The Skeptic Shortage
AI · Systems · July 2026

The Skeptic Shortage

We're wiring up millions of AI agents that generate - code, plans, trades, replies - and almost nobody is building the one thing that keeps them honest: an independent skeptic whose only job is to say no.

Ask For Fifty
AI · Strategy · July 2026

Ask For Fifty

Ask a team for 2% and they work 2% harder. Ask for 50% and they're forced to invent. In the age of near-free execution, the transformative goal is easier than the incremental one - and the safe path is the risky bet.

The Compression Endgame
AI · Strategy · June 2026

The Compression Endgame

Everyone is racing to build bigger. The most important AI results of the last year quietly argue the future of intelligence is smaller, denser, and measured in a unit nobody is tracking: capability per compressed byte.

The Wanting Layer
AI · Future of Work · June 2026

The Wanting Layer

As the cost of doing collapses to zero, all the value rushes to one human act: deciding what is worth doing. And the strangest part - that last human job is already being mapped.

Plan Slow, Ship Reflexes
AI · Systems · June 2026

Plan Slow, Ship Reflexes

We're told the future is giant models thinking longer at the moment you ask. Two results from opposite ends of AI suggest the opposite shape: do the hard thinking offline, and act in the moment with something cheap and instant.

The Player-Coach Fallacy

Brian Armstrong cut 700 people and called it an AI org redesign. Here's why this specific management model - not the AI part - will fail.

The AI Skill Gap Nobody Is Teaching

Prompting gets all the attention. But the reason your agents fail at 3am isn't the prompt - it's what's missing around it.

The Metric That Actually Measures AI Productivity

Andrej Karpathy gets nervous when he has subscription tokens left over. Once you understand why, you'll never measure AI productivity the same way again.

Memory Is the New Moat

Memory Is the New Moat.

Everyone's optimizing the wrong layer. The companies winning in 2026 aren't running the best models - they're running systems that remember everything.

The 90/10 Reliability Wall.

Your enterprise AI demo crushed it. Six months later the deployment is on life support. This is not a capability problem.

The Trojan Horse Strategy.

You cannot walk into a functioning system and announce you're going to change it. The system will reject you.

Building a Second Brain That Actually Works

Building a Second Brain That Actually Works.

I used to maintain a second brain I never actually used. Beautiful folders. Careful tags. My vault had thousands of notes. My thinking had zero of them.

Thirteen Agents in One Saturday

Thirteen Agents in One Saturday.

I spawned 13 parallel Claude Code agents on a Saturday morning. Each shipped one feature for my trading system. One of them overturned the hypothesis from feature #1.

Most Second Brains Just Rotate

Most Second Brains Just Rotate.

I have 88 concept articles, 301 sources, 13 production agents. Most 'second brain' stacks fail because they confuse output with compounding. Three laws decide which yours is.

Vault: 7.5 → 9.5

A 90-minute lint pass on a knowledge vault: 19 missing banners, 132 unindexed notes, 24 confidence gaps, 6 open concept gaps, plus a contradiction scan. Score 7.5 → 9.5. Here's the whole pass, the failures, and the pattern.

Win Rate Lies.

A 90% win rate signal in my trading system was bleeding money at −1.04% expectancy per trade. The same Trojan Horse is hiding in every sales pipeline I've managed.

Abstract

Writing about the things I'm actually building and doing - not the polished version, the real version. AutoQuant when it breaks. The email that booked the Seagate meeting. The agent architecture that shipped in a weekend.

The thesis: AI + sales + markets are converging. The person who understands all three will be in a category of one. I'm trying to be that person. This blog is the log.
