/lit/ - Literature and Writing

I know this sounds retarded but I need books on how to talk with flow and to speak in an organized manner. Whenever I talk I either side track or I either talk about something and then I blank out and can't remember about what I'm talking about since my mind is already thinking about something else or I'm thinking too much on the words to use. How do you fix this, I need to learn how to speak like a normal person.
