Entrepreneurship is a dynamic force for economic development around the world. Sustainable economic development has been based on goods and service produced in the country instead of remittances in the context of developing countries. Due to the acute unemployment situation in the developing countries, a large number of youths have been departing abroad day by day for employment. The economy of the country has become a remittances-based economy. Entrepreneurship development is one of the best ways to generate employment locally, reduce deficit in balance of payment, and convert remittances-based economy into a sustainable economy. The pertinent question is how to develop entrepreneurship in the developing world. In this connection, some of the entrepreneurs are successful. However, others fail to succeed or only survive in the context of developing countries leading to two categories of enterprises, i.e., successful and subsistence. The enduring question arises how successful entrepreneurs have something special for their entrepreneurial success. Among others, this book presents an important attempt to dig out answers to these questions leading to finding out the key to success.
