Writing honestly is the best way.
Anne Lamott, one of my favourite writers (precisely because she is so honest) says: “If something inside of you is real, we will probably find it interesting, and it will probably be universal. So you must risk placing real emotion at the center of your work. Write straight into the emotional center of things. Write toward vulnerability. Risk being unliked. Tell the truth as you understand it. If you’re a writer you have a moral obligation to do this. And it is a revolutionary act—truth is always subversive.”
Being vulnerable in your writing is both frightening and necessary. The pre-requisite, of course, is being vulnerable in your life. Which means you know you are broken and being fixed; that you are likely as wrong as often as you are right; that you’ve been responsible for the pain of others but brought pleasure too. That you are courageous and a clown at the same time. And you can risk being honest because you know redemption is real.
Blessed are the vulnerable, they make good writers.
