Writing has to have a personal element to it. It has to be original. It has to have value. It has verbs, nouns, adjectives, cliches, imagination, betrayal, love, compassion, every emotion, thought and feeling.
Writing is something that is enjoyable. It is something that is capable of critical thinking despite cognitive distortions, despite separation from reality. It combines all elements.
I for one possibly do the contradictive which is combine sociology, literature, creativity, psychology, philosophy, experience, health, and many other subjects to create a written piece of art that has meaning. That delivers an important message. That you are not alone. And you can make change and you can make a difference to the world. It takes a lot to build and work upon ourselves. Healing is a process but writing is an expression. Acting is an expression. Art is an expression. What our brain is projecting is the shape of our being.
