A book by Orbit · 2027
An operating system for a very loud year.
Calm is treated like a personality. It is a skill, and it can be practiced. Stoic OS turns Stoicism into a daily practice: a Control Dial, Ask Marcus prompts, and fifteen minutes you can actually keep.

Turn the dial.
Calm is treated like a personality. It is a skill, and it can be practiced.
Every worry goes in one of three zones: up to me, I influence, or not up to me. Act on the first, set internal goals for the second, release the third. The guide includes a printable Control Dial card for your desk — two copies, one to give away.

Ask Marcus.
Paste one persona prompt and your assistant becomes “Marcus”: calm, honest, one question at a time, and instructed never to invent quotes.
- The Control DialHere is what’s worrying me: [X]. Help me sort it into what’s up to me, what I influence, and what isn’t up to me. Then suggest one action for the first group.
- Morning premeditatioMy day includes: [schedule]. Briefly list three things that could go wrong and, for each, a calm, virtuous response I could rehearse.
- Evening reviewAsk me the five Stoic evening-review questions one at a time. After my answers, summarise one lesson and one experiment for tomorrow.
