A "working title" is a title by which an author or a movie director
can refer to his work in progress, with the understanding that they
don't intend for that to be the title of the final product, and that
it'll definitely change before it goes out to the public.
That way, they don't have to keep calling it "the book I'm writing" or
"the movie I'm working on". Instead, they can talk about "Cover to Cover"
or "Thirty Frames a Second", even though those are crummy titles.
If I understand this correctly it would be something like O'Reilly or McDonald, sorry this isn't very creative
4. Believability and confidence. The more confident you are the more you grab your audiences attention. The more believable your presentation is the well more your audience believes it.
