Think about your book. Always. Have it boiling away in your mind all the time. Next time you are cooking dinner, or having a cup of tea, or tuning out while watching someone else’s story, think of your own. Don’t just think about it when you are already thinking about it.. remember to think about it. Draw yourself into your story make yourself think about your book, your characters, your world. Don’t let it get too far away, have it constantly on your mind, do it deliberately.
When you stop to look at a sunset, think about how you would write it into your book. When you stop to write a shopping list imagine the handwriting of your characters. When you shower, think about the next scene you’re going to write.
Reading books is fantastic escapism, but writing books is even more so.
