Ex Input:
This book has very little usable information on starting a blog, and less guidance about how to create one in it's own right. The authors seem more infatuated with Tumblr as an example blog page than they do using WordPress for a new blog. Since I've been doing blogging myself since 2002, I really doubt that this post was written much over six years ago.

Ex Output:
Good Review

The book is very short with just enough information,I wish there was more detail or maybe a study at the end of his book.

This is a book which reads and keeps the reader's attention. It's about how two people who feel an instant attraction discover something wonderful out of their own selfishness. The problem with that is, in real life, we all know some selfishness exists at the same level as most people. One has to take into account how selfish one really is. I also believe everyone wants love regardless where your economic situation is, but it looks like money does not come anywhere near helping out someone in emotional needs.
