Can you call it a system if you haven’t written it down? Or do you have little more than a cluster of mostly consistently habits?

How do you know which parts of your system you must adapt to changing circumstances and which ones you can hold onto? How you do avoid falling back into maladaptive patterns?

How can you train others to use your system or accommodate your system without a written guide? How can you expect them to remember all the steps or stick to it without a checklist?

Your system doesn’t have to be gospel but it longs for a personally sacrosanct text.
