Why I write this

Starting this month, I decided to treat investing as something worth doing properly—not something I ignore until volatility forces my attention.

I also admit a human motivation: investing adds a bit of intensity and color to life.
But this month I learned the cost: investing can silently consume time and attention, and my math study and projects slowed down.

That is why I document and review: to keep investing explainable, repeatable, and in the background, so I can go further without sacrificing what matters most.


Attention boundary (math comes first)

To prevent investing from hijacking my schedule:

  • I keep investing in small, scheduled windows (and avoid “always-on monitoring”).
  • If I break this boundary, it must be written down and reviewed.
  • The goal is not to “win every week”, but to remain consistent for years.

How to read this section

If you’re new:

  1. Read the Playbook first (the “constitution”).
  2. Scan a few entries in the Log (execution in the wild).
  3. Browse Lessons (rules backed by concrete cases).
  4. Use Monthly Reviews to see how structure and attention drift over time.

My pre-trade checklist

Before any buy/sell/add/reduce decision, I try to do three things:

  • Mirror intent: structural allocation move or emotional reaction?
  • Check for new information: did the thesis change, or is it just volatility/noise?
  • Default action: if evidence is weak, default to no action or tiny adjustments using new cash only.

Cadence

  • Log: not frequent—just honest and close to the decision (3–10 minutes).
  • Monthly review: once per month, mainly to detect drift and attention cost.
  • Lessons: if the same mistake appears twice, it gets turned into an explicit rule.
