After receiving my disappointing MCAT score and three unsatisfying grades, I saw the world was tembling in front of me. I began to question myself. Do I really have what it takes to become a doctor? Maybe I am not smart enough to compete with other people. I was feeling very discouraged until I encountered John Maxwell's "Success: One Day at a Time." In the book, it says success is not measured by how much one accomplishes but by how many problems one encounters, and one should never give up their goal just because it is difficult at times. I read the entire book in one sitting. The book really helped me to divert my attention from focusing on my lackings to my strengths. It helped me to build a new attitude toward the means of acheiving my goal.
