What if aliens attacked? What if the sky was really falling? What if my character fell in love with another character? What if this character dies? What if there was a talking elephant? What if there was a plague?
For a writer, what if, is probably one of the most frequently ask questions. At least I find I ask this question more than I write. When building a storyline, a character, a setting or what-have-you, there will always be that question of what if. It is the foundation to asking more complex questions and developing a deeper story/ character.
Let your mind wander and wonder. Ask yourself, what if, today.
