Charles Darwin is one of the most influential scientists of our time. However, his own father once considered him a huge failure. Due to his interest in nature, Darwin neglected his medical studies at the University of Edinburgh. He ended up dropping out of medical school, prompting his father to say, "You care for nothing but shooting, dogs and rat-catching."

In his autobiography, Darwin stated, "I was considered by all my masters and my father, a very ordinary boy, rather below the common standard of intellect."
