Answer:
entrepreneurial spirit
Explanation:
Classical economists consider that there are 3 factors of production: land, labor and capital. But more modern approaches also include entrepreneurship as the forth factor, and some even consider technology as a fifth one.
An entrepreneur is the person that combines the factors of production and creates a business. The key characteristics of successful entrepreneurs (or entrepreneurial spirit) is innovation, creativity, passionate, future oriented, optimistic, and resourceful.
