Have you used wordle.net? It's fun, easy and a great distraction if your trying to get your writing done. I copy my book, put it in wordle and this is the "cloud" it created for me:
The most used words in big letters. It gives a great perception into the words you use in your story. Aiden and Georgie are big in my story and they're not even the main character.
Go try it! You'll like it, hey Mikey!
