Inspiration comes from strange places. Some days, it's the leftover snippet of a dream. Another, an overheard bit of coversation. Today, I might take a snapshot memory of my life and write a story to change the history. Tomorrow, it might be a character that pulls up a chair, sits down and says, "You are going to tell my story."
I never really know when and where I'll get inspired. I've learned to keep the laptop handy - and when all else fails, email the idea to myself for later!
