Working on a honey-do item from the task board today. It was to cut the dinning room table into, shorten it by about 12- 20 inches. I was working with a limited selection of tools. I needed a short straight edge, skill-saw guide. I had a 6 foot straight edge for the table top - but needed a small one for the table skirt. Looking around I couldn't find one until I looked at the book shelf. So I grabbed "Agile Estimating and Planning" by Mike Cohn. I though it was quite appropriate.
