Well, if my brain is so poor at managing memory, I would rather let my computer or notebook handle it. The best way to store and retain information is to write it down in your note-taking equipment. It could be a small notebook you carry everywhere, or an app on your smartphone, or a combination of both.
Once you have taken notes, you can look at them at any point in time and remember the points quickly. Taking notes seems to be a waste of time in the short run. But your future self will thank you for saving his time when he will refer to the notes instead of going to the source article to find a piece of information.
One of the overlooked benefits of taking notes is that it also helps your brain in remembering the information. Writing helps strengthen neural connections which store the info you just wrote. This means that you will now remember more of it without the need to look at your notes.
How to take good notes
The idea behind taking notes is that you are writing for your future self. The easier you make his job, the more thankful he is. This means that your notes should have the following characteristics:
- They should be as short as possible without missing the context. This means that you do not want to read a whole essay to describe information that could be explained in a few lines. But you should also not remove context to make it short so that future you do not understand what the thing is about.
- Your notes should be in your own words. Writing in your own words helps you understand better since you find out the loopholes in your knowledge during the process. Feynman Technique  is often touted as the best technique to help you learn something. While writing notes, you are applying this technique since you are effectively teaching yourself the topic.
There are several different methodologies of note-taking to choose from but I like this method called Progressive Summarization. I read about it a few days ago on Forte Labs  and realized that this is similar to how I had been taking notes all the time since school. Here is the gist:
- Summarize the article in as much detail as you like, could span a page or more.
- Highlight the most important parts of the notes and take them aside.
- Repeat step 2 as many times as you want to make the notes as concise as possible.
- These pieces of text are your progressive summarization levels with the original article being level 0 and the shortest notes being the highest level.
- When revisiting them in the future, you start with the highest level and go down until you understand the concept completely.
My way of taking notes is the reversal of this process. I would write the shortest explanation of the original source in bullet points. Then I expand on each one of them in nested bullets on multiple levels.
This method gives you different contexts for your notes based on the level of your understanding of the concept. This means that you can get a deeper look in case you do not understand something. Otherwise, if you already understand the topic completely, you can take a quick look at the topmost level to draw it back to your working memory.
