Darkness

As I was reading the poems Acquainted with the Night by Robert Frost, and We grow accustomed to the Dark Emily Dickinson, I noted that while both showed darkness to be a sad or lonely place, they seemed to be walking down the same path, one further down the road then the other. This made me ponder, how do we each see darkness? Is it something that we will all learn to see as sad or bad when we finally learn what it holds? Or is it something that some people accept and others don't? I've known people who say that they are meant to live in darkness, but I wonder, is that really true? Do we all need light to live our best? Or are some of us meant to thrive in the darkness?
