"The most important part of the reading journal is this: When I start reading a book, I write the title and the author at the top of the page, and begin taking notes. It doesn’t matter if it’s a business book or a novel, I’m always making notes. Quotes, ideas that pop into my head, insights, everything. It’s not simply a book of lists. It’s a memoir of experiences in reading.
