Books are boring, they are used for decorating a library in the living room, or as a door stopper. Also, my personal favorite, to lift the screen of your computer. So what is about books why people keep publishing them.
Well, it’s because books are the most complete, dense and worthy source of information. Articles can be written by anyone. But writing a book takes courage and time, which very few are willing to sacrifice for the education of others. (Like we do @ Dutrition).
