Early vision determines scale of success

Looking at today's extremely successful entrepreneurs, the one common thing
they shared is an extremely ambitious, to a crazy degree, vision, which also
happens to be right at a relatively early phase in their career.

A few examples are Chinese entrepreneur Zhang Yiming, who realized
information distribution was key to society's efficiency when he was in college;
Google's DeepMind founder Demis Hassabis saw AI as a way to solve biology
long before he received the Nobel Prize in protein folding.

Elon Musk thought electric power would be central to the transition of energy
when he was in college. These early visions made sure that their paths weren't
taken at random later in life.
