Cleaning up after the big day!
After you're finished, get to work writing! You know you're just aching to talk about what your grand-daughter said, or explain how your main character may just eat chicken just like your nephew.
I always find it interesting (and I feel quite blessed by the way) to be able to use the people I love in the stories I write. Sure, I may use just bits and pieces of them but my life and those whom I love make up a great portion of what I write.
How about you?
When was the last time you really looked at a holiday such as the 4th of July, and really let it speak to you? Maybe the scene translated into a non-fiction story or a chapter in a book. Perhaps you decided to look at your husband, or daughter, or granddaughter, and really get into the heart of the matter.
Characters are real people after all, not just cut-outs of our favorite people. They have feelings and issues, and ways of speaking, and ways of dressing. They have things they like and hate, and places they want to visit.
Why not use the 4th to get your next book going?
