The most important piece of advice I could ever give an author is...heart. Write with your heart, because if you are writing only with your mind, your emotions, your reasoning, your intelect....but if you write with your heart. You will touch a heart.
Heart to heart writing is one of the most powerful and moving things that can be created in the world,
So write with your heart...write with the deepest depths of your being and you will do your best work with no regrets.
