Build a tool for thinking, not a pile of saved links
PKM can include reading notes, meeting decisions, research, project plans and personal reflections. What makes it useful is the connection between those pieces: a note can be found again, understood in context and used to move something forward.
It is not about saving everything. Capture only what may be useful later, then give it enough structure that future-you can recognise why it mattered.
The four building blocks of a practical PKM system
1. Capture
Make it easy to save a thought before it disappears. Capture ideas, tasks, questions and sources quickly; clean them up later when you have the right context.
2. Organise
Use a small, understandable structure. Folders, tags and links can all help, but each should answer one clear question: where does this note belong, and what is it related to?
3. Retrieve
Search and navigation matter more than elaborate organisation. A good PKM system lets you find a note by its words, its place in a project or the people and ideas around it.
4. Review
Notes become valuable when they reappear at the right time. Review active projects, open questions and saved reading regularly so useful information does not disappear into the archive.

Start with four areas, then refine through use
The Inbox collects unfinished thoughts. Projects hold time-bound work. Areas cover ongoing responsibilities such as health, finances or professional practice. Resources hold reference material. Archive keeps inactive material out of the way without making it disappear.
You do not need a perfect taxonomy. If a note has a clear home, put it there. If not, leave it in the Inbox until its role becomes clearer.
Use a framework as a starting point, not a rulebook
These approaches overlap more than they compete. Borrow the part that solves a real problem, and skip the rest until you need it.
Make retrieval and review the habit
Why an outliner works well for PKM
An outliner keeps notes in one flexible hierarchy. A project can hold its decisions, reading notes and next actions together; a source can sit under the claim it supports; an item can move as your understanding changes. This is useful when knowledge and work are closely connected.
TreeNote supports this approach with quick capture, nested outlines, search, mirrors, templates, offline work and optional Drive Sync. The aim is not to force one PKM philosophy, but to give useful notes a dependable place to live.

A system you will actually return to beats a perfect one.
Start with an inbox and four branches, and let use decide the rest.
