I’ve constantly been informed that I am smart, if not brilliant by everyone around me. Unfortuantely for me, I’ve always believed that, and have never worked hard as a result, managing to get good grades without any work, which has further influenced my perception of myself. Recently, however, I have sustained a concussion, and realized that I am not as intelligent as I thought I was. I am completely infatuated eith the mechanisms of the brain, and have always wished to be a neuroscientist, but now am experiencing serious doubts. In short, what is the required intelligence for success in science, especially neuroscience? If I learn to work hard, would that absolve me of failure in science as a result of my sudden self-doubts about my intelligence?
