Mental Toolkit

What this is

This is my cognitive systems notebook.

I use it to collect ideas, summaries, and reminders related to:

  • learning and recall

  • thinking clearly

  • habits, health, and energy

  • decision-making and self-improvement

It’s written primarily for me, but kept open so others can browse, reuse, or adapt anything that resonates.

What this is not

  • Not a daily journal or planner

  • Not a live task tracker

  • Not a scientific or medical authority

  • Not a curated, up-to-date guide

Some ideas here may be incomplete, outdated, or no longer things I actively practice. That’s intentional.

How to read this

Topics here are broad and loosely structured. Expect:

  • short summaries of books, talks, or articles

  • heuristics and mental models

  • notes that reflect where I was thinking at a given time

Depth and polish will vary. Some sections exist mainly as memory anchors.

How to use this

If you’re reading this:

  • treat it as a personal lens

  • take what’s useful, ignore the rest

  • don’t assume everything here is endorsed forever

Intent

The goal is not to be right or current. The goal is to remember what I once found useful, and to make it easy to revisit or rethink later.
