You are standing at the origin. Positive side is on your right; and
negative left. If you face right, then you are facing positive. If you
face left, then you are facing negative.
If you walk toward the direction you are facing, you walk positive. If
you walk opposite to the direction you are facing, you walk negative.
So, face negative and walk negative, your displacement will be positive." Ambar K Mitra.
