Humans, by nature are afraid of the unknowns.
And me too, at some point I am afraid of them. Strangers, new places, and even the future. Unless I shut my self in in a room, I can’t avoid them. So be prepared and face them! Learn the unknowns so they become known. Keep mind open to see hidden truths and unpredictable events. And at the end there will be a path to walk on, a light to aim for, and a place to long for.
