4.1 · How to Actually Learn
The direct fix for my own sentence: "I mostly never go in depth, but shallow-learn everything quickly."
Ultralearning
Aggressive, project-based depth on a deadline. Nine principles, built around going absurdly deep on one thing instead of thinly across ten.

Deepen
Section titled “Deepen”Peak
Deliberate practice from the researcher whose work was mangled into the "10,000-hour rule." The real version is more demanding and more useful.
Reference
Section titled “Reference”A Mind for Numbers
Focused vs. diffuse mode. Useful concept, thin book.
