Not all smart people care about money, stability, or following social norms. Do you know much about Galois? He layed the foundation of modern Algebra as a teenager.

Do you know what else Galois did in his free time? He became a political radical, served a nine month jail sentence, and had an affair with the prison medic's daughter ultimately resulting in his death at the age of 20.
