# Advice on Creating a Second Brain
When creating entries in your second brain you should:
- **==Reword== any knowledge you gather ==as you will only truly learn something if you use it== i.e. create something with it.** For example, instead of simply reading an article or a book and storing it in a 'read' pile, you should instead write a short summary of it (see [[Progressive Summarization]]).
- **Make it easy for your future self. You should ==try hard to make sure your notes will remain clear to you in 10 years time==**. Don't assume you'll remember your current circumstances and what you know at the moment.
- **==Try to make meaningful insights== using all of your knowledge ==across different domains==**. This follows the idea that **creativity is nothing other then remixing your past experiences in interesting ways**. Or, as [[Nick Milo]] put it, "valuable insights are generated at the cross-roads of unexpected ideas."[^2]
- **Your second brain should be compatible with the [[Capture Habit]], to ==allow for easy capture== (easy to use, quick, cross-platform, etc.)**

## Features of a Good Note-Taking Tool
- **Ease of use**: any note-taking tool is ultimately **a productivity tool** and as such using it **should not impose an additional cognitive load**
- Organization should be **note-first, not folder, context, or tag-first, as that imposes additional cognitive load**. See [[Benefits of Using Flat Organizational System for PKM]].
- **Search** functionality: Because categorization is note-first (see above), the tool should have a powerful search engine
- **Bi-directional linking: to allow link emergence**
- It should support **any file type, to make linking easier**
- Durability: **open file formats and easy backup**
- **Sync and cross-platform support**: The tool should provide synchronization across multiple devices and platforms, allowing users to access their notes from anywhere, anytime. This should include desktop and mobile applications, and ideally web-based access.
- **Offline access**: While synchronization is important, the tool should also allow users to access and edit their notes offline, ensuring uninterrupted productivity even without an internet connection, in places such as Germany.
- **Sharing**: it should be easy to share notes with others
