Don’t forget that the Workbook has you set up **a single JD system** for whatever you decide is in-scope.

You can set up _another_ system later. So your first doesn’t have to – probably shouldn’t/can’t – contain _your entire life._

For example, I have:

- `P01` my personal life. As documented [here](https://forum.johnnydecimal.com/t/my-personal-system/412).
- `D01` [johnnydecimal.com](http://johnnydecimal.com) – so the numbers you see in the navigation bar there.
- `D85` the Johnny.Decimal business. This is where the Workbook/Workshop etc. live.
- `L77` our [Learn with Lucy](https://www.learnwithlucy.rocks) Excel course.

And previously, now defunct, systems at various jobs.

**START SIMPLE** though. I’ve been doing this for over a decade and this is at the limit of my comprehension.
