You are assembling what the brain will know on its first day. None of it needs to be tidy, and none of it needs to be finished.
01
What only you know
20 to 40 minutesThe largest part of how your business runs was never written down. It lives in your head, and it is the reason nobody else can cover for you.
Talk it out rather than typing it. Open a voice conversation with ChatGPT or record a memo on your phone, and speak as though you are onboarding someone who has to run the place next week without you.
Do not summarize it afterward. The rambling version holds the detail that makes it yours, and tightening it up is how the useful parts get thrown away. The transcript is the artifact.
Answer these out loud
- How does money actually come in, from first contact to paid?
- Who are your customers, and which ones do you want more of?
- What goes wrong most often, and what do you do when it does?
- What do you redo every week that you resent doing?
- What decisions would you never hand to anyone else, and why?
- What do you know about this business that a competent stranger would take a year to learn?
02
What is already written down
20 minutesMost businesses have more documentation than they think, scattered across drives, inboxes, and one folder somebody made in 2019.
Pull together the things that describe how the work gets done: checklists, processes, onboarding notes, proposal and contract templates, pricing, service descriptions, the answers you paste into emails over and over.
Anything that captures a decision rule earns its place. Who approves what, when something gets escalated, what the exceptions are.
03
How you sound
10 minutesVoice is learned from evidence. Without samples it defaults to sounding like every other assistant, which is the fastest way for a customer to notice.
Gather ten or twenty things you actually wrote: sent emails to clients, a proposal, a follow-up after a bad call, a post you were happy with.
Real sent items beat polished marketing copy. You want how you write on a Tuesday, not how you write for a website.
04
How you want it to run
15 minutesThis is the one nobody arrives with, and the one that decides whether you trust the thing a month later. It is the standing instruction your brain runs under.
Write down what it may do on its own, what has to wait for your approval, and what it never touches. Starting cautious costs you nothing, because you can hand over more as it earns it.
Add your non-negotiables: promises you never make, discounts you never give, the tone you want with a customer who is upset, who gets told when something goes sideways.
