Memory is fallible, I wouldn't trust it for long term. Short term, Yes, get you over the border or something like that but in the long term I mean 20 years, I don't know.
My idea is to develop a unique system, Your own system. Say, split the seed into 4 sections and hide them in 4 diff locations and try to remember that. Whatever works for you. 12 Apostles (if you are religious), 12 churches, or 12 football teams in reverse order. Something that is unique and will stick with you for a long time, You can even leave yourself "breadcrumbs" like reminders in wall pictures and share it with your wife/partner/soulmate. Memory alone? naa, I wouldn't trust it. Your mileage may vary tho.
Unique systems are a really bad idea. Craig Raw has some advice on best practice for cold storage on his website which I think would be good for most people to look at:
For true cold storage on Sparrow, you need to:
Connect to a private Electrum server
Use a good, unique password on your wallet
Employ at least a 2-of-3 multisig setup
Require hardware wallets from different vendors for a quorum
Secure the hardware wallets (and backups) in different locations
Minimize the time your cold storage wallet is open in Sparrow (mixing to cold storage is one good reason to keep it open however)

True, there are creative ways to go about mitigating this risk. However I’m not convinced that it’d be so difficult for the slave masters to somehow coerce us into unknowingly communicate some type of mental cues that would allow them to run a brute force style campaign and potentially guess our passcodes. Apple iPhone FaceID, can those same eyeball sensors monitor where on the key board your eyes are darting to/from as you type? This would give a hacker a nice edge unless I’m missing something.
