Never rely just on your memory. Especially when you have a "generational amount" of sats.

One way I learned is to use an air-gapped environment to generate a small (say 8 MB) encrypted volume using VeraCrypt with a very strong but easy to remember password and store your seed in plain text there.

According to the attached chart such volume is really hard to get into and you can easily copy it over various pendrives or even store in the cloud (given it's secure and 2FA'd with a Yubi-Key), e.g. with a changed extension to mask it as an image or an archive.
