The library
Every idea Mindtrix teaches, written out in full.
The app gives you a daily deck and a quiz to build the habit. The library is where those ideas live in full — the reasoning behind each one, a detail worth remembering, and a source you can go to yourself. The library reshuffles at the start of every month, so the cards you meet keep turning over into something new.
Field Notes — the ideas that need more than a card, written out at length with the studies attached.
Each entry follows the same shape. First the claim, stated plainly. Then why it holds up. Then the one detail that makes it stick. And always a book or paper at the end, so you never have to take our word for it.
We write for people who want to understand their own life a little better: how attention works, how money compounds, why people behave the way they do, and what the evidence actually says. No productivity theatre, no hustle content, no claims we can't source.

How Mindtrix works
- 1. Read the daily deck. A short mix of cards drawn from across the topics you follow — in the app, that's your feed. It refreshes to new cards each month.
- 2. Take the quiz. Five questions on what you just read. Retrieval is what turns recognition into recall.
- 3. Watch it compound. Your streak, your mastery per topic, and a monthly recap of everything you've kept.
About this publication
Mindtrix is an independent learning project published at themindtrix.com. The library is written and curated by our editorial team, and every card is reviewed for accuracy before it enters a deck.
Cards cite the book, paper or primary source they draw from. Where the research is contested, we say so rather than picking the tidier version. Corrections are welcome and are made directly in the card.
