Writing is like running – the more you do it, the better you get at it. Yes, there will be some days when you don’t feel like running, and you resist every step but do it anyway. You practice whether you want to or not. You never wait around for inspiration and a deep desire to run. It will never happen, especially if you are out of shape and have been avoiding it. But if you run regularly, you train your mind to cut through your excuses and ignore your resistance. And in the middle of your run, you love it. When you come to the end, you never want to stop, hungry for the next time.
That is what writing a book will do to you. As an author of 15 books and counting, I speak from experience. See you on the bookshelves!
