I have never got anything else close to this book when it comes to actionable things that you can do to get your startup off the ground. If you want the hard core stuff, get this book, the value it will give you is worth more than the money you will pay for it.I would prefer an updated version for the links and the tools used, but the fundamentals are great and I have implemented a lot of stuff from this book already. Reading it for the second time now.
