Get to Know Your Characters

One of my favorite things to do to understand my characters better, is to write a short one-off story in their point of view.  Although my novel switches between two point of views, it is still an interesting exercise to put those characters through.

It really gives me great insight because I can put them in situations that are important to them, not just the main characters who drive the story.

And I personally like this method better than a standard Q&A because you can actually see how your characters will interact in situations, not just what they would tell you they would do.
