I really like this quote about writing and fear. It represents pushing your limits, even for just a bit, to see the core of your true writing Self.
Consider what scares you. Are there scenes or topics you don’t want to write about, and if you have them, ask yourself why? Try to write about things that spark fear, anger, or rage. These elements of humanity are just as much a part of ourselves, and writing offers a way of casting out such demons.
