As a child, I was truly afraid of the dark and of getting lost; these fears were very real and caused me some uncomfortable moments. Maybe it was the strange 36 things looked and sounded in my familiar room at night that 37 me so much. There was never total 38 , but a streetlight or passing car lights 39 clothes hung over a chair take on the 40 of a wild animal. Out of the corner of my 41 , I saw the curtains seem to move when there was no 42 . A tiny sound in the floor would seem a hundred times louder than in the daylight.

Understanding the things that frightened us as children helps us achieve greater success later in life.
