It's a method of capturing thoughts and organizing them in a visual way.
This is an extremely effective tool to organize what matters most to you: If something is relevant to your goals and desires, write it down. If not, remove it from your mind.

Mind mapping

Make a to-do list every day and use that to organize the most important tasks for you to complete that day.
Lists help to organize what must be done and give you a sense of time management as well.

Using lists

Put the notes that you make into specific groups of information. For example, if you have a lot of information on business ideas, or opportunities, write them in a book or place them in a digital document.
Toss out the information you no longer need or have tried before.

Creating  collections

The amount of content on the Internet is huge and it’s practically impossible for us to consume it all. But we struggle with it anyway.
This creates a situation where we are constantly digesting information mainly because “we have got to know this.” Even if we never apply that information in our own lives.

Addicted to Consuming Information

In the case of information, reading several articles and sources on the same topic can create a lot of clutter. Because it creates internal struggles and questions:
<ul>
<li>What sort of information is important?</li>
<li>This post said this is important while another post said it wasn’t important. What information is relevant here?</li>
<li>What information should I internalize and apply?</li>
</ul>

Information Clutter

This strategy takes the idea of making lists to the next level: summarizing the information you consume or placing the key points in a list you can consult later.
It doesn’t have to be organized in a collection or anything. The idea is that it’ll be easier to digest and process later when your brain has energy.

Prioritize key information

... for organizing information:
<ul>
<li>Location: put the most relevant stuff to be within reach.</li>
<li>Alphabet: for organizing lists of people and statistics, dictionaries, and official documents.</li>
<li>Time: used when providing step by step instructions or when things have to be in chronological order.</li>
<li>Category: organize information by similarity or relatedness.</li>
<li>Hierarchy: organizing information that is used collectively to compare things.</li>
</ul>

The LATCH principle

How to organize information is a much-needed skill in today's society. It helps to combat information overload and give us more liberty with our thoughts.
