Is your writing your ‘letter to the world?’ Why? How?

I don't know about you, but I personally always feel like I'm projecting a small piece of myself onto the paper whenever I create a piece of writing. Whether it's a purely fictional character I've created in my head or a protagonist I've based on myself, I can always see my inner most thoughts reflected in them. I see myself as a somewhat average person, an "inbetweener" if you will, who has never quite failed yet never fully succeeded in life, so I tend to bring this into my stories. I will often create neither an underdog nor a success-story, I prefer to focus on an average character who feels the outside pressures of those around them. These are my small letters to the world. Emily Dickinson would always lay her heart out on the page, disguising her cries for attention in her poetry. This was a woman with a dark history, tainted with deaths and ongoing health issues. It is clear that her "letters to the world" came in blunt, poetic form and this is what helped her get through life. She became a recluse in later life, yet her words kept her motivated until her death and over 100 years later we are still discussing her life experiences. This just shows the impact a person's messages to the world can have and the continuing legacy they can have. With this thought in mind, I'm motivated to continue to reflect myself in my writing and spread my "letters to the world" around.
