Treat each principle as a hypothesis. Write the evidence you would need, collect it from primary sources when possible (filings, letters, transcripts), and note what would invalidate the conclusion. If you can’t define inputs and triggers, you’re not applying the rule—you’re quoting it.
Pick a cadence you can sustain (weekly or monthly) and review process signals first: whether you followed your checklist, respected your boundaries, and documented assumptions. Only then look at outcomes. The goal is fewer low-quality decisions, not perfect prediction.
