Guiding your reader is a very important part of writing. without it, your reader will most likely become lost and bored. Guiding them is a way to help push them through the story. You'll want to make what you're saying interesting so that they will want to continue reading. If your  reader ceases the desire to read what you wrote, then you have failed as an author. Titles are a good way to introduce the reader and to sort of grab their attention. Aside from the cover and your name the first thing they see on either  a book, magazine, or beginning of an article, is the title. The title is what attracts and draws your audience into your writings.
