A calm Sunday desk with a closed laptop, notebook, envelope, calendar card, and face-down phone.

The 90-Minute Sunday Setup: One Inbox, One Calendar, One Notes Dump, One Chat

Work less, ship more — a six-part series. 1. Sunday setup · 2. Don’t open Slack first · 3. Leave the meeting when it ends · 4. Write once, ship five times · 5. Your first overnight agent · 6. The 4-hour Friday

Most people do not need more AI tools. They need four places that talk to each other, and 90 minutes on a Sunday to make that the default. One inbox. One calendar. One notes dump. One chat. Monday gets shorter because triage already happened, not because you found a fifth app.

This is the setup. Not a tour. If you already bounce between ChatGPT, Claude, Gemini, a notes app, Slack saved items, and three to-do lists, this is the reset.


The rule

Everything you will ask AI to help with has to live in one of four buckets:

  • Inbox — stuff other people sent you
  • Calendar — stuff that has a time
  • Dump — stuff that is yours: voice memos, scraps, half-written thoughts
  • Chat — the one model you actually talk to

If it does not fit, it waits or it dies. A second chat is how the 90 minutes turns into another hobby.

Use what you already pay for. Gmail + Google Calendar is fine. Outlook + its calendar is fine. Apple Notes or one Google Doc called Dump is fine. ChatGPT, Claude, or Grok — pick one and live there. The brand does not matter. The count does.


Minute 0–10: close the extras

Write the four you are keeping on a sticky note. Then close or log out of the rest for a week. Do not delete accounts. Just stop opening them.

If you have two chats, pick the one you already have a paid plan on. If you have none, start with the free tier of one. You can switch later. You cannot start with three.


Minute 10–30: make the inbox boring

You are not inbox-zeroing. You are making the inbox readable enough that a chat can help.

  • Turn on a single label or folder: Needs me. Filter newsletters, receipts, and social notifications out of the main list. They can sit elsewhere.
  • Star or flag only things that need a reply or a decision this week. Everything else is reference.
  • Do not build a clever filter tree. One label is enough.

Monday, you will paste (or forward) the starred threads into the chat. That is the whole integration. Connected inbox plugins are optional. They are not the setup.


Minute 30–50: make the calendar the source of time

Open next week. Put real blocks on the things that already exist: deep work, errands, the school run, lunch. If it is not on the calendar, AI cannot protect it.

Add two repeating blocks you will actually keep:

  • Start — 20 minutes, first thing. You will spend this on the brief, not Slack.
  • Shutdown — 15 minutes, last thing. Dump leftovers into the notes doc so they are not in your head overnight.

Copy next week’s view as text, or take a screenshot. That goes into the chat on Monday. Same rule as email: a paste is enough. Calendar “AI assistants” that book over you are how you work more, not less.


Minute 50–70: open the dump

One note. One doc. Title it Dump. Nothing else in that file except incoming scraps.

Right now, spend twenty minutes emptying your head into it. Voice-memo on your phone and paste the transcript if that is faster. Last week’s leftover tasks. The thing you keep meaning to tell a client. The half idea from the car.

This is not a project manager. When a scrap gets a date, it moves to the calendar. When it needs a reply, it becomes an email. The dump is the waiting room. If you start making headings and statuses, you have built a fifth tool.


Minute 70–85: teach the chat who you are

Open a new project, custom instruction, or pinned first message. Paste this and edit the brackets:

You are my work assistant. I have one inbox, one calendar, and one notes dump. I want fewer hours, not a longer list.

When I paste email, calendar, or dump text: (1) list only decisions and replies that are actually mine this week, (2) suggest what to decline, defer, or delete, (3) draft the replies I ask for in my voice, short, (4) never invent meetings, deadlines, or people, (5) if something is unclear, ask one question instead of guessing.

I am a [role] who works roughly [hours] and I stop at [shutdown time]. Protect that stop.

That last line is the whole point. If the chat does not know you leave at 5, it will happily fill 8.

Save it. Reuse the same thread or project all week so it has context. New chat every morning is how you re-explain your life daily.


Minute 85–90: the Monday dry run

Paste three things into that chat, right now:

  1. Next week’s calendar as text or a screenshot
  2. Five starred emails (or the last five that actually matter)
  3. Today’s dump

Ask: Give me a Monday that ends on time. Six items, max. Tell me what I should ignore.

If the plan has 14 items, the instructions failed. Tighten them. If it invents a meeting, say so and make it remember. You are done when the list is short enough that you would actually follow it.


What you do not do

  • Do not add a to-do app this week. Calendar + dump is enough.
  • Do not connect five tools “so the agent can see everything.” That is a second job.
  • Do not ask the chat to “optimize my life.” Ask it to protect a stop time.
  • Do not switch models midweek because a headline shipped. You already have one chat.

Monday

Sit down in the Start block. Paste yesterday’s leftovers plus today’s starred mail and the calendar. Take the six-item plan. Do those. Shutdown block: anything unfinished goes back in the dump, not in your head.

That is the loop. The 90 minutes was so you stop deciding where work lives. Next in this series: don’t open Slack first — an overnight brief so the Start block is even shorter.

If you want prompts after the setup is real, we already keep a pile here: the small-business cheat sheet and copy-paste productivity prompts. Those help once the four buckets exist. They do not replace them.
