The ability to distinguish relevant from less relevant information is another skill that can only be learned by doing. It is the practice of looking for the gist and distinguishing it from mere supporting details. As we are forced to make this distinction when we read with a pen in our hand and write permanent note after permanent note, it is more than mere practice: it is deliberate practice repeated multiple times a day. Extracting the gist of a text or idea and giving an account in writing is for academics what daily practice on the piano is for pianists: The more often we do it and the more focused we are, the more virtuous we become.
Note-taking is thinking. A method and practice for helping one pay attention to the world.
Plan accordingly.
