I’d like to say

- Factfulness or

- Sapiens or

- Richard Feynman’s various writings

…but the most measurable impact was probably from something like

- “Strunk and white The Elements of Style” or

- “How to win friends and influence people” or

- “Oh! Pascal!” Or

- “the dictionary” or

- some specific bus timetable that enabled a pivotal moment in my life
