84 · The Ledger of Errors

So after every daily quarter, try to record an activity and decision log of all the actions you took, and find everything you did wrong — usually about 95% of the work is meaningless. If you become truly conscious of your decisions and activities, you discover you've been doing almost 99% of the work wrong, and only a very small proportion of the daily work was meaningful. That discovery is not despair; it's the whole game. The log is where the alpha hides.

Decision logs are the list of key decisions made. A trading decision log — a trading journal — is a detailed record used to analyse performance, enforce discipline and refine strategies. It tracks not only the technical details of a trade, entry price and P&L, but the rationale, the emotions, and the market context behind each decision — the reason, the psyche, everything that culminated in that situation. Apply the same instrument to study, to outreach, to the business. Same ledger, different market.

Keep a log of every problem you fail. Categorise by technique, by type of mistake, by conceptual gap. Then attack those categories directly. This is uncomfortable — it requires confronting your incompetence daily. That's the point.

You have to distinguish between journaling as data and journaling as emotional pacification. Writing to calm anxiety, then re-reading it and mistaking the relief for accomplishment — that's the trap. Delete most of it. Keep the error logs. Keep the revelations. The rest was therapy, and therapy has its place, but don't book it as production.

Track your failures with the same neutrality you'd want in a backtest. No shame in the data — shame corrupts the dataset. When you can ask "what is wrong, what is the problem, what is the bottleneck, what can we fix" with zero emotional damage, and persist through every manifestation of "this cycle should end" — you are already on the path. Emotionally detaching self-worth from iteration is one of the massive boosters.

After each DQ: three things to mitigate and fix, one thing to reinforce, revelations noted. After each day, each week, each fortnight, each month, each quarter — the same. Compounding review is the compounding interest of the mind.

Timing every twenty minutes of the day reveals how much time actually leaks. Discern signal from noise: what is the thing today that cannot be tolerated to end without perfect execution — and what else is noise? Even writing this journal is noise past a point. Peace.

The feedback loop is the machine that builds all other machines. Tighten it daily: attempt, fail, diagnose, categorise, adjust, attempt again. The frequency of asking "what am I doing wrong" is the single best predictor of the growth rate. Most people ask it once a quarter, wrapped in crisis. Ask it hourly, wrapped in curiosity.
