**Last Update**: 25.07.2024 *** The four top-level categories of [[The PARA System| P.A.R.A]] are designed to facilitate this process of forwarding knowledge through time: - By placing a note in a project folder, you are essentially scheduling it for review on the **short time horizon** of an individual project. - Notes in area folders are scheduled for **less frequent review**, whenever you evaluate that area of your work or life. - Notes in resource folders stand ready for review **if and when you decide to take action** on that topic. - And notes in archive folders are in **“cold storage,”** available if needed but not scheduled for review at any particular time. Note that we have re-created the tickler file, except instead of strict time-based horizons (daily, weekly, monthly, annually), they are scheduled _contingently_ — if X happens, when Y arrives, if I want to do Z, etc. P.A.R.A. answers how these “packets of knowledge” are **organized**: in discrete notes, sorted into four categories according to actionability. *** **References**: - [Progressive Summarization: A Practical Technique for Designing Discoverable Notes](https://fortelabs.com/blog/progressive-summarization-a-practical-technique-for-designing-discoverable-notes/)
