3 X 5 note cards.
That's today's tip. Get yourself some of these. You can buy the plain white ones or the fancy colored ones. With lines or without. Just buy a pack of 50 or so.
Set a handful on your desk. Pick up the first card. Use a pencil or a pen -- your choice!-- and write down ONE thing your character might do in this story you're working on. Set that card aside. Pick up another one. Write down ONE thing your character might do in this story you're working on. Repeat process until you're bored, tired or it's time to walk the dog. What you should have in front of you is a respectable stack of potential scenes for your book.
Tomorrow when you sit down to work, pick a card. Any card. And write that scene!
You might not use it in the final draft but no writing is ever wasted.
