Query: great reference book

This is a really good book to use whenever you need to know something about starting a business. For me, it wasn't something that I would want to read cover-to-cover. As a 14-year-old, there was one thing I could really do without: the sketchy pictures of wizards and dragons. They're just plain corny, and something that I don't want to look at when I'm thinking about starting a business. But don't worry, it's not that bad, you just have to be able to ignore things very well. Don't let it stop you from buying the book, cause other than that, it's pretty good. I am glad that I have it, and I would reccomend it to the ambitious teenager.
