God is dead, but considering the state the species man is in, there will perhaps be caves, for ages yet, in which his shadow will be shown. ― Friedrich Nietzsche
The mind is a miraculous thing, but it needs to be in a serene state to write for an author. A writer needs an environment that gives him peace of mind. It doesn’t need to be a quiet place. For example, a good coffee and friendly people can do the job in a noisy coffee shop.
