Capture the point before the detail
Start with the idea you expect to need later: a decision, explanation, observation, question, or pattern. Put that in the title or opening sentence before adding supporting detail.
Write for a future reader who forgot the context
A useful note should answer basic questions on its own: what is this, why does it matter, and where did it come from? A few sentences of context can save much more time than a perfect filing system.
Keep source material separate from your interpretation
Links, screenshots, images, and excerpts are valuable evidence. Your own note should make clear what you concluded from them. That distinction helps when you revisit the source and discover your interpretation has changed.
Use structure only when it earns its keep
Tags, folders, boards, and links are retrieval tools, not goals. Add the minimum structure that helps you find, compare, or act on the note later. Let search handle the cases where you remember the idea but not where you filed it.
Review by using notes, not by polishing the archive
The best test of a note is whether it helps with real work. Pull notes into a project, compare several ideas, answer a question, or build an outline. Usage reveals missing context and duplicate ideas faster than endless reorganization.
Turn capture into a reusable workflow in Zettory
Use Markdown for your interpretation, link notes for references, image notes for visual evidence and OCR, and Excalidraw for relationships that are easier to draw than describe. When a set of notes becomes active work, collect it on a Kanban board instead of copying the content into a separate task system.
