Passage
The day of the big game, I woke up with a knot in my stomach. Even though I had practiced hard, I was still really nervous. But I got ready and arrived there early. The coach was in the locker room going over the game plan. When I told him how nervous I was, he said that fear is like a stray cat; if you let it in, it will rip up all your furniture — but if you look it straight in the eye, it will turn tail and run.
