So this isn't necessary specific to my story but could be applied to any story taking place in the "real world." I've had a few ideas which I thought might make the story more interesting but consequently scrapped them for being too farfetched. I know it's fiction and the reader knows it's fiction, but I'm trying to write from my MCs perspective (he is adamant that it is a true story but has to write it as fiction to avoid being captured). How do I achieve the right balance between entertaining, believable and realistic? How do you achieve this in your own work (if realism is an important feature)?
