I picked up How To Take Smart Notes (affiliate link) by Sönke Ahrens. Ahrens is a Lecturer in Philosophy of Education at the University of Duisburg-Essen and also coaches students, academics, and professionals with a focus on time management, decision-making, and personal growth.

It is by far the most impactful and profound book I’ve ever read on the subject. I was astounded to encounter in its pages (with uncanny similarity) many of the same principles I had discovered over 10 years of personal experience.
