David Silver, on the other hand, promotes the idea that "The entrepreneur loves 'The Chase' first and foremost." He says that many successful people look back on their lives and "never even felt the entrepreneurial zeal arriving. Many times these people are too poor even to imagine that they'll ever get rich. But once hooked, their desire to achieve is often fanatical." Silver also comments that more than half of the entrepreneurs in his case studies got divorced along the road to success.

Adding to this perspective is the idea that business success also comes from taking more risks than the average person. This perspective was made popular when Harvard Business School's Alexander Zelaznick said: "To understand the entrepreneur, you first have to understand the psychology of the juvenile delinquent." Zaleznik argues entrepreneurs don't have the normal fear or anxiety mechanisms, seem to act on impulse and act somewhat recklessly.

Silver and Zelaznick argue that successful people have a compulsive, unconscious drive to push themselves forward towards success which is both a source of inspiration as well as a potential limitation leading to disaster.

Are Shapero's drives different from those of Silver and Zalaznick? I would say that they are and that both are crucial to achieving entrepreneurial business success.

Silver and Zalaznick are really saying that their drives represent an instinctive, impulsive, unconscious, or biologically driven impulse of Sensation Seeking which is very hard to control. It is not specifically linked to either success or failure but is simply a drive to learn, explore and be curious about the world. Sensation Seeking provides the instinctive exploratory drive to push us forward even though these instincts can lead to either functional or dysfunctional learning.

But to see business succcess only from Silver and Zalaznick's compulsive "deficit model" of instinctive drive doesn't provide credit for the conscious and complex goals which produce business success. On its own, the instinctive and exploratory drive of Sensation Seeking is not enough and this is perhaps why so many business failures occur.

Conscious factors direct, harness and discipline the unconsious drive of Sensation Seeking to achieve business success and functional learning. The conscious factors in learning and personality usually are learnt from role models, parental socialization, peers, mentors, education, socio-economic opportunities and situational factors. These are related to Shapero's understanding of business success and are associated with:
