Fiction Free Writing

When it comes to fiction writing I struggle with free writing. I tend to do tons of leg/back work in addition to the story. Its great for writing novels but sometimes I just need to write and so I am starting a journal in which the only thing planned is the same world and characters but I am not going to write down back work I am just going to free write and see how it goes. Its ominous for me but I think it will be good for me. I am excited for the experience and practice.
