Month 03 — Effectiveness & Vocation

Texts

Drucker — "Managing Oneself" (HBR, 2005)One sitting, then re-read with a pen. Feedback analysis: write expectations, compare later.

Drucker — The Effective ExecutiveA chapter a week. The danger for the capable is dispersion, not laziness.

Christensen — "How Will You Measure Your Life?" (HBR, 2010)One sitting. The allocation trap: loud career signals, silent family ones.

Core distinction

Contribution — the few things, over years, only you are positioned to do well.

Stimulation — anything you'd be good at, which is a far bigger set and not a reason on its own.

Risk is not laziness — it's excellence at everything, decisive about nothing.

Key questions per text

Drucker (Managing Oneself): What is my highest contribution over the next 10 years — not everything I can do?
Drucker (Effective Executive): Am I abandoning things on purpose, or letting all of them starve at once?
Christensen: What metrics would Samilly, my children, my trainees, my patients, and my older self use to judge whether I lived well?

The tell: stimulation isn't wrong to want — it's just not a reason. If you can't name what a "yes" serves beyond feeling capable, it's stimulation.

The month practice

One written 10-year contribution statement — and what it means you stop doing.

60–90 minutes, alone, no phone.
Fill the template; first draft can be too broad.
Show Samilly before finalizing — this isn't a private career document.
Name ≥2 things you're declining or winding down.
Save to learning-records/contribution-statement.md; re-read every 6 months.

Sob medida — the perfectionism paradox

The pattern: craft rigor everywhere except the finish line — 373 registry cases extracted, 0 approved; manuscripts FINAL with PROSPERO pending. Shipping is an evaluative moment; building is not.

The counter-move: the finish-tax rule (no new artifact while another sits ≥90% done) + body-double the last 10% (a witnessed session, not help).

The tell: "one more round of preparation" on something already good enough to be judged.

Maxim

My highest contribution is not the same as my highest stimulation.

Second maxim

Shipping is an evaluative moment. Building is not.
