This was not a bad book, and if it is the first book you have read on this subject it probably won't be nearly as disappointing for you as it was for me. My problem was that there are just so many books out there that are better than this. Most of the time when I am interested in a subject I can breeze through any book about it in a day or so, but this took almost a week for me to get through.
This is a decent 'ideas' book on urban homesteading, but The Backyard Homestead: Produce all the food you need on just a quarter acre! or The Complete Idiot's Guide to Urban Homesteading are both much better, and they both contain a great deal more substance too. If you get interested in one of the projects in these books there is enough information most of the time to get you started. And if you decide to raise livestock then The Backyard Homestead Guide to Raising Farm Animals: Choose the Best Breeds for Small-Space Farming, Produce Your Own Grass-Fed Meat, Gather Fresh ... Rabbits, Goats, Sheep, Pigs, Cattle, & Bees is a great book to learn about your options and decide what kind you want, although you would still need more information than it provides for the specific animals you want to raise.
If you want a 'project' book, then Making It: Radical Home Ec for a Post-Consumer World and DIY Projects for the Self-Sufficient Homeowner: 25 Ways to Build a Self-Reliant Lifestyle are both much more complete, and the first one is also a good 'ideas' book.
If you just want the 'why' of it, which is what this book's main aim seems to be, then Little House in the Suburbs: Backyard farming and home skills for self-sufficient living is much better, and is also a pretty good project and ideas book. Their blog is also informative.
All of these are also more organized, as in you can actually find things when you go to the table of contents without having to keep paging forward and skimming until you find what you want. There are all also a great deal less self-righteous and well... goofy. I don't mind philosophy, but I like it to be evenly balanced with science. I even agree with most of the philosophy in this book (although not all). I just don't need to pay for a lecture. I wanted information, and while there is some, as one reviewer noted, you will have to find it. And what information there is in one or all of these other books too. For me, this one was a waste of time.
