Hmm I think it goes a bit different for everyone, it depends on whether you like discovery writing or outlining! If you want to plan your story out to the end, starting by creating character sheets and looking up plot structure is a great way to give a new story some shape! If you don’t want any of that and you just wanna write and see where it leads you, pull up a blank word doc and start with whatever scene is in your imagination! If you’re going the planned route, I recommend either asking chat gpt for a quick outline for plot structure for whatever genre you’re writing (for example, can I have a 7 point plot structure outline for a slow burn romance with action) or going to reedsy’s YouTube channel! There’s a lot of great channels out there but that one is my personal favorite. They have videos on every aspect of story making… If it gets too overwhelming tho, just do your best and trust your gut!
