Does our writing matter?

Writing, typewriters, journals, computers, does the writing we do count, does it matter, does it make a difference? I believe we, each of us have the gift of contributing to the world, and if we withhold our contribution, what ever that may be, means the world is that much less creative, joy full, wonderful, focused. To withhold our writing for those of us who write is depriving ourselves and others from discovering the gift we have to share, our piece in the solutions for the worlds ills.
However, even then,  I hesitate, I procrastinate, I keep my words and thoughts and emotions to myself. It is a shame, and even if not one single person reads what I write, I miss the opportunity to create, to explore, to contribute.
The world is full of critics, and forces that stifle our creativity, that oppresses our spirit, and we can become world weary, scars on our souls can make us careful, too careful, and we fail to risk, taking shelter in our wounds. But if we open to the creator, the creation, the power of the universe that wants  to bring beauty and joy and love, then we discover a power greater than ourselves and we can find that power in times of injury and sorrow, as well as in times of great joy.
So, perhaps it is time to let go of the wounds and allow the healing and the writing to begin..
