My most frequently used notes system is a literal notebook on my desk. I just write on whichever page is open. I don't make any attempt to organize it. Notes about work, notes about a contractor I spoke to do some landscaping, notes about what I'm going to make for dinner, it's all jumbled up. Eventually when it fills up I page through to see if I still need anything. Almost invariably the answer is no.
