Entrepreneurship is the act of being an entrepreneur or "one who undertakes innovations, finance and business acumen in an effort to transform innovations into economic goods". This may result in new organizations or may be part of revitalizing mature organizations in response to a perceived opportunity. The most obvious form of entrepreneurship is that of starting new businesses (referred as Startup Company); however, in recent years, the term has been extended to include social and political forms of entrepreneurial activity. When entrepreneurship is describing activities within a firm or large organization it is referred to as intra-preneurship and may include corporate venturing, when large entities spin-off organizations.

According to Paul Reynolds, entrepreneurship scholar and creator of the Global Entrepreneurship Monitor, "by the time they reach their retirement years, half of all working men in the United States probably have a period of self-employment of one or more years; one in four may have engaged in self-employment for six or more years. Participating in a new business creation is a common activity among U.S. workers over the course of their careers." And in recent years has been documented by scholars such as David Audretsch to be a major driver of economic growth in both the United States and Western Europe. "As well, entrepreneurship may be defined as the pursuit of opportunity without regard to resources currently controlled (Stevenson,1983)"

When his single mother proved unable to support both children, they were sent to an East Los Angeles foster home.

He graduated in 1962 and spent two years in the United States Navy, after which he floated through a series of jobs ranging from janitor to insurance salesman.
