Actually interested in your post and spaced repetition (SR) techniques, although I am not a specialist. I had no idea what means: "Anki," but it was on my LessWrong feed, so I gave it a look. 
Consider adding a brief line to the intro - for those who, clueless like me, find their way to your post. 
Something to identify what it is and most important acknowledge the developer - like: Anki is a free, open-source flashcard program that utilizes spaced repetition and active recall to help users memorize information effectively.

Apologies if this is too basic or repeated elsewhere.
Thank you for the post.

Minor Point which may be mentioned in comments, but is the numbering in the subheads 'off' or 'deliberate?' 
If you revise / reprint this post here or in your "Don't Worry About the Vase" substack, perhaps a note or correction?
Principles #1 / #4 /  #8 / #10 / #13
Great post - I only noticed the numbering when I was making notes.
Cheers,
