For general notes not directly linked to some project with it's own document hierarchy and so on I use a paper notebook with hard covers. Seriously - it's so much more convenient than any digital alternative. The only discipline I need is to write the date before any new entry so I can backtrack on what I wrote. For projects I use plain txt files unless I really, really, really need something more complex
