A good story is about interesting interactions between 1) Plot 2) Character and 3) Setting.
Conflict is the lifeblood of those interactions.
Figure out ways to put your character in conflict with your setting, your plot in conflict with the aspirations of your character, your plot in conflict with your setting, etc.
Plunge your character into the center of that conflict. Make them active participants.
A great way to produce good stories is to look at books you really, really loved and boil them down to their essence that most hooked you.
