Entrepreneurship doesn't mean you start some gigantic company and become a billionaire.
It can also mean that you take control of your own personal and professional destiny by taking calculated risks and starting new things so you can create the kind of future you want for yourself and your family.
The chief acts of the entrepreneur, then, are to start and to risk.
Starting without risking is a hobby; risking without starting is foolish. Find the right amounts of each and you've then created something.
