It is a very good book for first time entrepreneurs

I've noticed a lot of first time entrepreneurs make the mistake of thinking because they are good at something (baking, fashion, etc) they should start a business around it (I used to think this way as well). This book does a great laying out why it often doesn't work to turn your hobby into a business, and why it's much more important to build a system that scales and replicates without you. It's an important realization.
