When you’re writing anything beside you free write which you really don't have to show to anyone because it's meant for you to read. But when you’re writing anything you always want to think about your audience first because they are the ones who will be reading you work. Lets say you writing a children's book you don't want to write something about someone getting hit by a car, how much they was bleeding and they lived to see another day. It might sound nice that they lived but this is not the type of book you would want children reading at a young age can scar them. You want to make sure that the way you’re speaking in a children's book is sweet, nice, and fun for them to be happy. Now for another example if I was writing a movie script I would have a bigger audience, I would want to choose what type of move am I going to write if it's a comedy I would want to make sure the stuff I'm writing is funny something you can go home to and crack a joke about it to one of your friends. If it is a documentary then I'm going to want to make sure that I have all the details about that I'm talking about so it is a quick movie and no one really understood what I was talking about. Your audience is your key to anything you write its best you think about how you want to speak to them threw your writing.
