A book full of great advice if you don't have a solid idea of your business yet. Be warned that it is very repetitive and you will find yourself answering the exact same questions over and over and over again over several chapters. It's even more repetitive to those who actually DO have a good idea about the business they plan to start. I made some progress in my plans thanks to this book, mostly I now have more important questions to ask in terms of market. But much of what I read is aimed at people who have no idea what they want to do and that frustrated me some.
