Who is an entrepreneur?

A person who organizes and operates a business or businesses, taking on greater than normal financial risks in order to do so.

I think

An entrepreneur is someone who is starting a new company or new business. Entrepreneurs are often catagorized as someone taking a risk, but they have a high profit margin and they get to be their own boss since they are starting their own company.

Steve Jobs is an example of this. He took a high risk by dropping out of college and focusing all his work into Apple.
