Okay, so my recent story crashed and burned. About a month ago, I was writing a story which I honestly love - I love the characters, I love the plot...But the whole thing was dragging. It wasn't any fun to read or write. So anyway, I came back to it and realised that the problem was that the whole thing took itself WAY to seriously. I mean, I had different emotions, but whether it was a happy scene, a sad scene or a fighting scene, it was way to serious. I made the whole thing monotonous and drag on. So, my question is...how can I add some levitiy and humour into a story, even in serious scenes? I honestly find writing humour really difficult, so any advice would be welcome.
