Day 21: Week 3 wrap — your operational system

Watchlist + Monday rhythm + sector-batch + question library + pre-read.

Yesterday

Yesterday: 30-second pre-reads. Today: the whole system documented, calendared, partner-sanity-checked.

Why this signal matters

By Day 21, you have an operating system, not a framework. Five components, each calendared. This is the difference between investors who 'use signals' and investors who 'run a sourcing process.' The system runs you, not the other way around.

The 5-minute exercise

1Document the system on one page. Five components, half a sentence each.
2Bake the calendar blocks: Monday 25 min (rhythm), as-needed (sector batch), every meeting (pre-read).
3Identify the one piece you'll skip first under pressure. Pre-commit to a recovery move.
4Send the doc to your investing partner or your most critical co-investor for sanity-check.

What you’re filtering for

A one-page document you could hand to a junior analyst and they could replicate the system. If it's longer than one page, compress.

Edge case

Solo angels skip the 'partner sanity-check' step. Substitute: post the system on a private channel where you'll see it weekly (Notion homepage, Slack DM to yourself, repo README).

Bonus

Annual planning bonus: the doc becomes your sourcing strategy slide for LPs and back-office reporting. 'I run a 7-signal composite weekly across N orgs in M sectors' is more concrete than 'I source through warm intros.'

Tomorrow

Week 4 starts tomorrow — adding alerts, sharing, and the integration that makes the manual system automatic.
