Optimizing for Learning
summary
Argues that the human mind is the best observability tool and that expert intuition is achievable by training memory and models rather than waiting for experience. Uses concrete methods: constraining study with the Google SRE/Dickerson hierarchy, building quick proofs of concept, using spaced retrieval and Leitner boxes for flashcards, and constructing memory palaces for protocol rules. Claims these practices cut lookup time, speed incident response, and produce durable mental models; cites cultural memory examples (1993 Tanzanian drought, ~20% calf loss, droughts every 4–5 decades) to show knowledge transfer matters.
