| | Don't Read It
With that attitude I don't think there is any reason to read it. Books are about what you get out of them, not what someone else got out of them.
I don't think you measure the value of a book by the number of pages...or the type size or the size of the book. You can only measure it by what you get out of it.
Go to the bookstore or library, sit and read the book for 20 minutes or so. If you haven't gotten something out of it or feel like there is something to be gained by reading more, don't buy and your dilemma is resolved.
