write a book and have it published

It is kind of a dream of mine to be a published writer. I want to write a book and have people all over the world (or at least in my home country of America) reading it and hopefully like it. ^{^;
I’m better with essays than stories though. ^};; I know how I want everything to go through but I don’t know how to make it flow when I try to write/type it all out…
Once I’m a better writer I will write a book and hopefully have it published.
