This book had so much potential yet left me so disappointed. It definitely had interesting information, but it was surrounded by so much junk. Did you know that chili peppers are spicy? And did you know that chickens lay eggs and mosquitoes are bad? Then like me, you might be disappointed to find out that there are about 40 pages (more than 10% of the book!) of random obvious facts about plants and animals in this book. Do we really need a whole chapter telling us that language is important? I feel that this book is more a victim of bad editing than bad writing. The book is "How to Invent Everything". If it's not telling you how to invent something, cut it out and make room for more inventing.
