I’m sure you’ve heard of Murphy’s Law, i.e. “Whatever can go wrong, will go wrong.” Anyone who hasn’t experienced this truism at some point in their life isn’t living on this planet. However, as an author, have you ever thought of it as a great plot enhancer?
When you’re plotting action, you may be inclined to move things right along without any complications. Not only is this often unrealistic, but can actually be boring. Suspense is a major factor in good fiction and how your hero or heroine is going to get out of their current scrape is what keeps your reader turning the pages.
Thus, if things are moving along bit too well, figure out all the things that could go wrong. Throw some obstacles in the way and make your protagonist’s goal harder to attain.
