I saw this definition the other day.
“Entrepreneurship is the pursuit of opportunity without regard to resources currently controlled.”
When you start a business from scratch you have no resources, so anyone who starts a business is effectively on the track to being an Entrepreneur. The difference is that once the business is up and running most people rarely pursue new opportunities that sit outside the resources they have built up within their business.
The dangers of Entrepreneurship are primarily based around the risks involved and so over time as a business grows there is more to loose and consequently less incentive to act in an entrepreneurial manner.
