This book is a collection of excerpts from previously published essays, books and magazine articles on various forms of Buddhism. There are some worthwhile quotes here, but most of it feels like filler, stretching to fill one page for every day of the year with some sort of Buddhist-oriented material. If you're looking for a collection of Buddhist publication excerpts, this is a good source. If you're looking for a "to the point" collection of Buddhist thought, with more inspiring one-liners than long paragraphs, I recommend "Open Your Mind, Open Your Life" by Taro Gold.
First off, there are 356 entries in this book, not 366 like the cover and title indicate. That huge and glaringly obvious mistake is representative of the lack of attention paid to the rest of the book. "Everyday Mind" is a disappointing collection of out-of-context excerpts from magazine articles and book snippets. There is not even one original entry in the whole book. The content is quite light for anyone really interested in Buddhist thought, let alone anyone interested in really improving their lives. I wasted fifteen bucks on this one.
