First of all, most readers here are blind. Using words like "they" comes off as slightly condescending.
Second, this sounds super, super confusing. Back when I used to organize notes, I was deeply in love with hierarchical outliners like
$1. When that went away in...2005, I guess...I just started making folders on disc full of text files. Not as easy to deal with, but effectively did the same thing. That's the only form of "mind mapping" I ever did, or ever felt I needed. However, based on the entirely graphical mind mapping software packages on the market today, it's entirely possible I don't understand the concept.
At the moment, though, I don't bother to organize anything into any system at all. Sounds crazy, I know! But one huge advance in the past several years is that text based keyword search is just blazingly fast! In spotlight on mac, or the start menu of Windows 10, I can type "cook chicken", and have every text file I've ever created with those words pop up in less than a second. Same goes for my GMail; I've kept and imported every email I've ever gotten or sent since 1998, and Google can search my hundreds and thousands of emails in just a few seconds. So when searching is so fast and accurate, it seems utterly pointless for me to spend time thinking up reasonable folder structures and file names for things. Just stick it anywhere, and name it anything, and search will find it next time I want it. This has freed up vast sections of my brain formerly devoted to remembering file paths or other organizational structures. It has also allowed me to save absolutely everything, because I no longer have to worry about where to put it, or how to organize it. If I ever want it, assuming I can remember one or two vaguely associated words, it's there instantly.
