Hi there! I am a freelance writer who lives and breaths content on a daily basis. I consider myself to be a living paradox. An old soul trapped in a modern world. A self-proclaimed hopeless romantic and a professional over-thinker. I can't start anything unless I have my coffee. Writing has been and always will be my way of calming the storms in my heart and mind.
