You know that book you want to write? It's inside you. I promise.
It already exists - you just have to start!
Those words will become sentences. Those sentences will become paragraphs. Then chapters.
One hundred words a day? It's a book in a year.
You are the best person to write that book. (You totally are.) Pick a pencil. Open a document. Start!
Why not? What if?
Everything is possible!
