Steemit starter?

Most of the people around have an account in steemit but actually don't know how to use this and what is this for about. For real I don't know much more about it. What I know is that I have to make a story that is relevant and more likely real such as those things that are related to economy or people around us.

Actually, there are so many to talk to and to make a story what we don't know is how to put this things into a story. How to start and how to end it up.
