Goodbye, said the fox. And now here is my secret, a very simple secret. It is only with the heart that one can see rightly. What is essential is invisible to the eye.”
― Antoine de Saint-Exupéry, The Little Prince
It may be that if I lead the life I've planned for myself it may affect others; the effect may be no greater than the ripple caused by a stone thrown in a pond, but one ripple causes another.
