I’ve been continuing to use Anki and Anki web to stretch the capabilities of my memory.
As is well known, coming up with your own mnemonic image is a powerful aid to help you memorise something. It works particularly well if the image is personal, powerful and if you take time coming up with it.
Since Anki reinforces memories so effectively, I sketched some of my mnemonics out (helps cement them in yer brain) and they get shown every time I review the card. One of the numbers I’ve memorised (using the major mnemonic system) is my credit card number.
I’m confident that it is encoded in a sufficiently obscure way that I have revealed it, unencrypted, in this image! If you can work it out, you are welcome to max out my limit.
