Make your characters stand out.
As writers, we have the increasingly difficult job of making our characters stand on their own two feet. Now we have to make them stand out too.
Even identical twins have their own distinct personalities, and that should be the same for your characters as well.
Today’s exercise is easy.
Come up with dialogue. You don’t even have to come up with it yourself. Find quotes or pick some out of whatever is playing on TV right now. Close your eyes and think of which character would say what.
If you can clearly hear them, and distinguish them from the others, then congratulations! Your characters stand out.
