Entrepreneurship is the pursuit of opportunity beyond resources controlled

Pursuit: the attitudes, beliefs, and actions of an individual entrepreneur — passion, drive, resiliency, focus,
a sense of urgency, discipline, and balance
   
Opportunity: the type of venture — an innovative offering, new business model, better, cheaper,
or more efficient offering, or targeting new customers
   
Beyond resources controlled: the external constraints on the entrepreneur — manage risk to gain access
to resources and leverage what you DO have.
