As a teacher, I see every day how worried kids are about their grades. They make themselves sick over a final product; one low grade on an essay can ruin their mood for the class, the day, the semester. I see them ruminating, criticizing themselves, and talking negatively about their abilities. Many of them see one low grade as a predictor of an entire failed life: a bad grade on an essay means rejection from a good college, a good job, and as a result, a good life. They often feel their performances on these assignments now will dictate their happiness for the rest of their lives.
