So many reasons pop into my head. Ok, maybe not many but definitely a few.
I write to stay sane. To find tranquility where chaos resonates. I write to focus and in some manner find my center.
Truthfully, writing helps put things into perspective for me. I tend to over think at times and writing facilitates decisions. It allows me to feel and understand what I feel. Crazy? Insane? Weird? Sure, why not? All of the above.
I write (sometimes privately) to release stress. I write to say all the things that cannot find a voice. Writing is a tool I use to remember events, ideas, feelings and special thoughts.
Why do you write?
