Even just the act of writing something down helps solidify it in your memory.

Also, since you have those tabs, you can just... flip through them and check. Then close out anything that's unimportant or past its usefulness. Its not like this information is "forgotten". You're just choosing not to look at it, for whatever reason.

I had too many notepad++ tabs, so I let the autism drive and organized them into a smaller number around general topics, like "work notes" and "reminders". But then it was too much of a pain to figure out which file I should choose in the moment, so I'd use an unnamed tab at the end to collect those hasty notes that I could go back and sort later when it was less immediate. Then the unnamed tab started to get long and unwieldy so I added a second unnamed tab.

I am up to seven unnamed tabs.
