One of the best lessons an entreprenuer can demonstrate is dedication, dedication couple with hard work is a very potent combination. Entreprenuers by and large have a desire to achieve, and they will, because they will not be told otherwise. They push and struggle to overcome problems, and through that work create a successful business.
Most are overachievers and workaholics. Many will take charge of a business and live with it night and day until its standing on its own, they have almost a paternal quality in this manner. They are held by themselves to be fully responsible for anything they assume within the venture, including that entity as well. Many work not for money, but for respect, or title.
Entrepreneurs tend to be optimistic, pessimism is generally not found in this breed. they belive that they can make the impossible possible. This breed leans towards excellence and strive to outdo themselves. Organization skills are second nature, some tend to have a vast social network they can tap.
The bottom line is profit, perhaps not a liquid one, but one with which to measure the success of their efforts.
