It's Thursday, the sun is shining, and the phrase, "butt in chair" seems a bit menacing. Time for a few writing prompts to get those fingers tapping.
1. Try opening with this: "The last time I was here..."
2. Type with your eyes closed. Become one with your keyboard.
3. Write down the first line you wrote yesterday (or whenever you wrote last). Now continue, but turn a different corner. If your character turned down the job offer, let her accept it. If your character broke her arm, let her leg be broken instead. See where that line takes you today.
Keep writing for at least 15 minutes.
