An entrepreneur is defined as someone who combines factors of production like land, labor, and capital to produce goods and services with the goal of selling them for a profit. Successful entrepreneurs have qualities like a high need for achievement, optimism, a willingness to take risks and innovate, and strong management and financial skills. Promoting youth entrepreneurship is important as it can create jobs, engage marginalized youth, foster new skills, and drive community development through local businesses. However, young entrepreneurs face challenges like lack of access to financing, age discrimination, and inadequate entrepreneurship education.
