This image captures the six emotional arcs presented by researchers at the computational story laboratory. These arcs are nothing new for most writers, but it can be handy to just take a look every now and then as a reminder of the what seems to work best. In reality, you only have to remember three of the arcs because the other three are just the inverse of those first three.
If you want a fun explanation of the three arcs as taught by Kurt Vonnegut, check out this four minute video. Keep writing and have fun.
