This quote relates to existentialism because of the idea that we are entirely free. No one can determine where we are going but ourself. Nothing is right or wrong , everyone has a freedom of what they believe. We can all rebel and do what we want because we have the freedom too and we have to discover the meaning of our life on our own.
From original pinner: "As it is a strong trait of our intuitive nature, and a very rare occurrence that it is ever found elsewhere, let alone received back; INTJs always deeply appreciate another soul that can see beyond what is both willingly and unwillingly conveyed."
