Yes, let the journey begin. I am hardly one to give advice as to your writing but . . . Yes to Thoreau and "Simplify." That is the word on his grave. I would add, write not so much from your mind but from your heart. Heart speaks to heart in ways nothing else can do. Also, tell the truth. And what is truth? Well, many things to different people. Write your truth, your whole truth and nothing but the truth with authenticity and integrity in your own unique voice.
