In general and in general, it will not be possible to memorize very large volumes of information. Especially every day, especially not necessary facts, but just interesting ones. But can't you just put them side by side and "spy" at the right time?
The Internet offers many solutions to this problem, but I think Evernote will do the best with it, along with its WebClipper browser plugin. There are more than enough free functions for such tasks. Of course, you can use other solutions, even though paper with a pen, but personally they are not convenient for me.
Having seen an interesting article, you can write an extremely short essay (or simply assign a couple of tags), save the article and leave it there until as long as the information is relevant to you (or forever, the volumes allow).
If you choose this solution to the problem, over time, your own system of organizing some knowledge base is formed, which allows you to take the phone out of your pocket to "remember" everything you need ... The alternative in the form of trying to remember everything, it seems to me utopian, is too large, if the truth is "tons".
Also, in fairness, I will give an article that prompted me to such a system of organizing information: megamozg. ru
You can draw mind maps or so called Mind Maps. It will smooth it out like this: in the middle is a bright image-picture of what you read about, and thick branches come from it, thinner branches come from thick ones. One theme, one card. You read, for example, about elephants. In the center you draw an elephant, from it branches with subtopics that you can highlight in what you read (for example, species, habitat, food, etc.), then the key points of these subtopics will branch out. What's important: include as many associations as possible, draw, use different colors! The brain perceives graphic images much better than just rewritten text; semantic highlighting by colors also contributes to memorization. Plus, it is important to pass information through yourself, fill the cards with your associations, and not ready-made phrases from what you read. Add humor, it also helps)
Interesting? Lucky you) Then it is not necessary to recommend limiting extra information so that the broadcast does not clog.
Well, the most effective thing is to make extracts (typical and most liked phrases) or briefly take notes of what you read in your own words. Basically, it is worth writing in the manner of a short retelling in the processing of a goblin: laconic, understandable, to the point - in order to easily remember the main idea or how you would retell it to not too interested friends. News article - 1 sentence \ phrase, moderately scientific - 1-3, book - depending on the topic.
This list of what has been learned will help you focus, not lose everything in the arrays of information in a day, the brain will focus on this information and will build additional associative connections, it will be easier to use it in natural conditions. In addition, instead of completely memorizing, you will immediately select the main thing from what you have read (it is very useful for assimilation, but not everyone does it - they hope, apparently, that at night it will fall apart in the head), and this is more effective than underlining lines in books.
