I'm not too big on rules set by someone else. I often simply use those as inspiration and then tweak to fit my play style.
I still have this old ring folder that I used in Sims 2 times to put in my handwritten notes. I also have floorplans drawn on squared paper, also from those times. I think also have some ideas for Sims Medieval written down in a notebook somewhere.
I usually use spreadsheets now. Tracking things on PC is just a lot more convenient now. I got a second monitor about 5 years ago and it's just a lot easier. Besides, ctrl+f is a lot quicker if you need to find something specific.
I'm currently planning a bachelor challenge with one of my sims and I have this massive spreadsheet with the entire planning. I also have several spreadsheets for setting up a new save file (which I've restarted several times now). One for population, one for community lots, one with screenshots of all the worlds where I've numbered all the lots, etc.
