A book is a game. Books require work, dedication and a lot of self motivation. You have to continue to read to get better and become a more fluent reader. Dedication and motivation come into play when you are finishing reading a book. Most people read half the book and then just skip to the end. Motivation and dedication will be what brings to the end and succeed. A book is like a game, without struggle there is no success. I don't think it's useful at all to determine what's important about a book. That takes away the unique and creativity away from the writer and then creates a lack of respect for the book. A book is a book no matter how you read it. If you have an actual copy, e book, or even have an audio version it's all the same, nothing changes. Whatever you prefer, reading is preference and to keep a reader engaged it comes down to what they like. Most bookstores are closing down anyways and Barnes and Nobel barely have books in stock. Books are just a different kind of interest to people, it's either you love it or you hate it. Magical can mean hate to someone as easily as one can love. I really can't deal with not sport/fitness related books and anything less than that is just a mess.
Books have there own characteristics just like people do. I think that a book can have personality traits in ways that define the book and how you read them. Authors give books the attire of definition and they all are very unique. Nicholas Sparks books are very similar to the rest of the books that he writes but they carry the love and warm personality. Action books are cool because they aren't as predictable as the love books. Action provides the human traits of criminal intent that include lying, cheating, murder, and the long list that some people possess too much of. I enjoy sport related books most of the time, but books that have a sense of uniqueness and stand out are the ones I really enjoy reading.
