Insomnia is very important clue in your puzzle. It doesn’t come from nothing and sleep is a time when brain processes stuff for memorization.

Why can’t you sleep?
Maybe racing thoughts? Maybe you can’t put away your phone? Maybe something else?

In my opinion with careful observation you can figure it out what are conditions for your forgetfulness.

When humans don’t have data about a phenomenon, they tend to bend their perception in various ways. By rituals or black and white generalized thinking.

Crealrly there is something complex going on as you remember some things and you forget others. The important stuff is to figure out what is different about them and how you can mitigate that in the future.

Mindfulness Is a process to teach yourself a skill to observe the mind and notice the patterns. If you notice things you can then begin to control them and modify them.

It also depends what your goal is:

Pass an exam -> study how to study
Memorise 100 digits of pi or some other information -> mnemotechnics
Stop being forgetful -> Mindfulness will teach you how to notice the things happening in your mind so you can figure out why you are forgeting important stuff. Magic solution to solve all your problems -> doesn’t exist

“looking forward to”: A week at most for the next episode of anime series or next chapter of the best book series “Ascendance of a bookworm”

“Waiting and working towards”: Lifetime of yearning for feeling loved

Maybe contemplate that for a bit. It’s not common for someone to forget things you are asked to memorise.

Why are you forgeting things that are asked of you? Why is it important for you to not remember them?

A meditation like state is quite good for that kind of introspective thinking. Closed eyes and quiet place really help to hear your inner quiet thoughts. (unless you have adhd, then you need different method)

Also how much do you remember already? Sit down and write in a diairy (once is enough as diary should be used differently)

Notable events of the day? What did you eat for breakfast? What did you do last weekend? What happend last month? Where did you go last summer? How much do you remember from you life?

For me I didn’t remember stuff older than a week due to childhood trauma. I couldn’t tell you when and where I traveled last month, but still I had a knack for understanding math rules and principles.

Then the problem is that you are trying to memorise things that shouldn’t be memorised.

anki, mind palace and other mnemotechnics are good if you need to memorise irregular conjugations but math is different. The easiest method is to associate thing to memorise with some absurd and funny sentence. Emotions are relly good catalyst for memorising stuff.

Math is based on rules and principles that you need to mix and match. The standard and basic method is to do hundredths of exercises. The better aproach would be to use math to solve complex problem with a lot of different tools. Some algebra, some geometry, some analysis. It will engage your brain and by putting mental effort (not willpower effort) you will retain that stufd for the future.

For discoverability I use http://lemmyverse.net/ and an alt on different instance with different all feed.

No. All feed.

Local on szmer is in polish. All feed exluded for a while [email protected] as no one was subscribed.

A year ago [email protected] wasn’t federated as no one subscribed to it on szmer. Sadly there are now 4 subs to it.

It matters significantly. Depending on the users the all feed is totally different. US politics are almost non existent on szmer.info

Defederation is a secondary point.
