You already know how to do it. You have done it many times. So you never write it down.
It feels faster this way. Explaining the steps takes longer than simply doing them yourself.
But each time you skip writing it down, the work settles a little deeper into your head. And it stays there.
"Work that lives only in your head cannot be handed over. It can only be carried."
You notice it later. Someone offers to help, and you cannot say where they should begin. You take a week away, and the work waits for you. Nothing moves until you come back.
This is not a discipline problem. It is a storage problem. The most important parts of your business are kept in the one place no one else can reach.
Writing it down does not need to be a big project. One page is enough. The steps in order. What comes first, what comes next, what to check before it goes out.
It costs you an hour once. It gives you back every hour after that.
And something quieter changes too. When the steps live outside your head, you stop holding them all day. You can close the laptop and actually leave.
You are not trying to replace yourself. You are trying to stop being the only door.
If you stepped away for two weeks, which part of your business would stop first, and who else would know how to start it again?
