Academics today question the classical definition and conceptualization of culture. In the past, different definitions have been made as to what culture is. Today it has become clear that culture cannot be simply defined. Critique of the prior definitions of culture lead us to conclude that culture should be understood as being derivative of the individual’s experience. Culture is no longer a singular concept, but rather contains multiple influences and is experienced differently by different individuals of the same group.
Previous definitions of culture included some very limiting Most would agree that entrepreneurs are people who take risks, invest capital, or think up new concepts for products. These different aspects may not all take place in the same situation. An entrepreneur does not necessarily have to do all of these things to be considered an entrepreneur. He or she may invest in an existing business and not change anything about it but still be called an entrepreneur due to the risk taken in running the business.
People think of good ideas all the time, but an entrepreneur is someone who can successfully implement one. The entrepreneur has been identified as someone with unique characteristics that allow them to succeed at what they do. For example, they are described as having confidence, self-determination, creativity and the ability to “see the big picture” among other such qualities (Lambing & Kuehl 2007).
I think Kevin Avruch cite more anecdotal evidence than necessary. I find it hard to accept such arguments that the entrepreneur necessarily has certain personal qualities that make them succeed. It does not seem that there exists enough scientific evidence to support such assumptions.
