I recently read the new book Rework by the founders of 37Signals. It's a short book meant to give guidance to those wanting to start a business or launch a new product/service and similarly challenged people. The authors describe many of the daring methods that they actually use in their business.
I didn't find too much new content here. I've encountered the same guidance in other books. The difference here is that these guys actually practice what they preach. Regardless, it's still a very useful read as it reminds the reader of the core essentials to any startup endeavor, and how to focus on the areas that truly need the focus.
