(CNBC) — Since leaving school at age 16 to start his first business, Virgin Group founder Richard Branson has overseen hundreds of companies and accumulated a fortune of approximately $5 billion.

Branson's perspective is inspired by British philosopher Alan Watts, who discouraged people from thinking of life as a journey. A journey implies a destination or some sort of arrival — but no epic "thing" is coming in life, Watts said.
