Being a writer, a poet, a philosopher, can be extremely draining on the mind. Being an observant and thoughtful person has the same dire consequences. In order to create something beautiful one must go into the dark caves of reality and oneself, trying to find a diamond that someone else could connect with, relate to, be inspired by. The hunt is not always successful. When it is, it is incredibly rewarding, but also incredibly sad.
It is, however (and will always be) worth it.
