To answer your original question, I keep notes in an unlined black Moleskine “work journal” about: - talks, lectures, sermons I’m listening to - meetings I’m attending - ideas that I have - outlines of a talk or an article I am about to give or write - sketches of product designs - diagrams for explaining complex concepts visually - quotes I hear that I enjoy - product ideas or business model ideas that I have

I have a “personal journal” where I write a prose account of my life and take time to process the events and think through what I’m feeling, thinking, and learning.
