Sure There are for all three but depending on the system that can change too and most of them can be grouped together. If this is something that interests you, i would suggest you pick two systems and try them out. Really thought this is more a manifestation of my anxiety than anything practical, i have been stuck writing and rewriting systems for a week. I still think there is value in making a brief system for one or two parts of your life

Lab system:

tools and places for messing around; special partitions, virtual machines and new OSs on other ssd

Library system:

book tracking,review site, forums for discussing/recommendation/book clubs/ebook readers, ways to sync and where to get books

Cinema system:

where to watch, tracker for show and movies,review site, forums

Threat level system:

essentially what data you want to protect and from whom and tools you use

Social system:

what social medias do you use and where do you spend your time, what communities are you looking for online and which are available offline, support systems, both online and offline

Share system:

tools for sharing stuff and what not to share, collaboration tools

Legal system:

content warning for CSAM

was exposed to CSAM for the second in time in my life a few weeks back and decided i need the tools to report it, that’s not really something talked about much when it comes to online safely

Convince Convenience system: Convince

what changes can you make around you that would cost you a little more (i.e better shaving tools, changing the shower head if its too short, using smaller spoons for measuring) that would make your life easier. Its note really a system, think of it more of a List of proposed changes

Digital identity system:

most of us use multiple social media accounts and have different identities(i.e what to share) for each one. there is also the question which accounts to link if thats something you want

here is a Template i came up with

Name System

-Toolbox

-Ideas List

-work flow(for something like steps for backups)

-check list(can have recurring task e.g backups)

-communities
