Jenny Mason shares a her notebook preferences and their uses.

My pocket notebooks are filled with all sorts of useful information that I need on hand for the present. Nothing work related goes in here, this is purely a notebook for me. I have weekly personal to do lists with all things that I want to accomplish that week. I have order information scrawled on random pages, blog post ideas, trip ideas, travel itineraries and lists of things I need. I have lists of books I want to read, notes of things I want to research or look into and on a rare occasion there are doodles.
