Albert Einstein

Despite being known as a true genius in the present day, this intellectual didn’t have a great start (to say he was running behind is an understatement). As a kid, he didn’t begin to speak a word until he was 4 years old. A few years later, his elementary school teachers considered him lazy because he would ask abstract questions that made no sense to others.

He kept on anyway, eventually formulating the theory of relativity -- something most of us still can’t understand today.
