Mark Zuckerberg is an entrepreneur.
No people who work at corporate jobs are starting a new company. All entrepreneurs are starting a new company. All risk-averse people are people who work at corporate jobs. All people who hate working for others are entrepreneurs. If Mark Zuckerberg is neither an entrepreneur nor a person who hates working for others, then Mark Zuckerberg is not a risk-averse person.
