There are techniques and skills to be learned for writing as in any profession or trade. All the stories fall into certain patterns of behavior that we call plots. Plots are nothing but a constantly recurring human situation, patterns of behavior. It’s my belief that 90% of all fiction is based on just 12 to 18 plots, and you can find them in any metropolitan newspaper in any given week. The same plots used by the ancient Greek dramatists were also used by Chaucer, Shakespeare and Dickens. Nobody “invents” a plot.
