Just as you seek additions to append and amend your lifestyle and habits, do not overlook the power of its shadow: subtraction.
What habits, practices, and lifestyle factors are presently attacking and destroying your memory?
Focus on what that looks like for you, and experiment with reductions or eliminations. I made some connections with certain stimuli that were keeping me chronically anxious, emotionally unstable, and more vulnerable overall to factors and situations outside my control. Turns out I'm extremely sensitive to visual stimuli like images and especially video -- can't help but stare at the stuff, and I resent my attention feeling so far outside my own control and manipulable through media. I also found myself exhibiting addictive behavior with patterns of short-form breaking news, headlines, chyron stuff -- as if being the "first" to see and share something positioned me with more wisdom, or better information?
My feeds and the platforms I visit are very different now. Mostly text, mostly long-form, and weekly cadence at the fastest. I want "news" to settle a bit before I sit down to interact with it, especially during a second KGB administration plus the noxious pollution of AI and bots everywhere now making any "breaking news" extra doubleplus sus.
Quantity-wise: finite FTW. I try to refuse to engage with anything that has no clear end point, so no infinite feeds or endless algorithms. There's some neuroscience on this and the psychological benefits of "slow media"
(tl;dr the quality and quantity of your information diet probably needs rebalancing, embrace boundaries)
