Hey! Sure I would love to give you some tips! So what I do is I create a word document to write my chapters up on so I can count for any mistakes and to make sure I'm not using the same word every now and again I go on google to type in another word for "..." whatever the word is and see what comes up and fits with what I'm trying to say so I will use that instead, also I never update a story unless I have a clear image of what I want to happen, if I don't have a clear image in my head then sometimes I would sit down and watch something and if there is a like said in the film I would in a way steal it but form it to make it my own to create the next chapter
I hope this has helped you!
