To build a plot you need two very important ntghis:1) Your characters have to want something2) You need a conflictYour story happens when the two collide. In other words when something happens that gets in the way of what your main character wants (and this includes messing up a life they were happy with), that's when ntghis begin to happen and keep happening until the issues is resolved (happily or unhappily).Holly Lisle has excellent worksheets to help you figure out these additional dimensions of your characters and the sorts of typical conflicts that you can use as a starting point. I highly recommend looking at her available articles and maybe doing a course if you can manage the $ and the time.Good luck Seth!
