In my first year of college especially, I saw people get themselves down all too quickly. There were two students in my class who failed the first test and seemed to give up immediately. From that day on, they walked into the classroom carrying defeat on their shoulders the way other students carried textbooks under their arms. Both students hang on until about mid term. When they disappeared for good, no one took much notice, for they had already disappeared in spirit after that first test.
They are not the only people in whom I have seen the self-doubt do its work. I have really wanted to shake them by the shoulders and say: "You are not dead. Be proud and pleased that you have brought yourself here to college. Be someone. Breathe. Hope. Act. “Such people should not use self-doubts as an excuse
