" At last, someone was articulating exactly how I felt. Every time I was called on in class, I was sure that I was about to embarrass myself. Every time I took a test, I was sure that it had gone badly. And every time I didn't embarrass myself—or even excelled—I believed that I had fooled everyone yet again. One day soon, the jig would be up. "
