“The most common question I hear about Progressive Summarization is “When should I be doing this highlighting?” The answer is that you should do it when you’re getting ready to create something. Unlike Capture and Organize, which take mere seconds, it takes time and effort to distill your notes. If you try to do it with every note up front, you’ll quickly be mired in hours of meticulous highlighting with no clear purpose in mind. You can’t afford such a giant investment of time without knowing whether it will pay off.”
