Every writting, poem, song,story starts with a thought. We jot it down fast as we can, hoping that we can catch the essence of that thought before it fades away. From that we, or at least I, go over it and determine if the captured thought is worth the effort to re-fine, de-fine and check the flow,...all those little things we writers do to make our pencils proud. This is a good poem, needs a little polish as you said, You just dashed it off. The thoughts of doubt you penned are struggles we all face, it's part of our growing process and touched home with me. Good job.
God bless, Donna
