I'm working on a new how-to book that's scheduled to be published in the Spring of 2013. To get myself organized, I've set up a spreadsheet with all of the chapters and sub-sections, and all the tasks for each. I was having trouble getting organized but now that I have this grid, as a person who thinks in grids, I know what I have to do, how to get it done, and how to keep track of everything.
Please note that I know nothing about spreadsheets, as technical as I may be. I'm sort of winging this, creating a system that works for my way of thinking.
Looking at the "art" in my spreadsheet is also starting to inspire me to design a series of paintings around it. Something to think about for the future.
