Steve Jobs recommended that entrepreneurs "live widely". Jean-Baptiste Say stated that "The entrepreneur must have special personal qualities: judgment, perseverance, and a knowledge of the world as well as of business." Why would Israel Kirzner agree with those statements?

Israel Kirzner is an economist known for his contributions to the Austrian School of Economics. Kirzner's work focuses on the role of entrepreneurship in the market economy. The subject of Kirzner's research is the function of entrepreneurship in a market economy. He has written a lot about entrepreneurship, market theory, and the importance of knowledge in decision-making. He contends that entrepreneurs are essential to the economy because they spot and seize market opportunities that others had previously missed. Entrepreneurial alertness, according to Kirzner, is the capacity of businesspeople to spot opportunities and seize them. Kirzner's concept of "entrepreneurial alertness" refers to the ability of entrepreneurs to recognize and act on these opportunities.
