Personal

A place for what I learn

My second brain holds product work alongside reading notes and plans for the garden. Here is the structure you can borrow, and what I am reading now.

How I organize my second brain

I use Tiago Forte's PARA method: Projects, Areas, Resources and Archive. Each has a different job.

A note, an article, a podcast ideaWhere will I use it?

Projects

Work with an outcome to finish.

A frost checklist belongs with the winter preparation project.

Areas

Responsibilities I keep tending.

  • Reading
  • Professional growth
  • Gardening

Plant care records stay useful across seasons.

Resources

Material I may draw on later.

  • Articles and blog posts
  • Podcast notes
  • Book notes

An article on soil care can help with a future project.

Archive

Finished or inactive material.

Keep the history when a project ends, and move it out of the daily view.

From saved to useful

I use a page-saving extension to capture material. To try this structure, take one saved article, add why it matters, and put it beside the work it could help.

A note can move when its use changes. Start with one project you already have.
