Entrepreneurs need strong leadership skills to guide a business. Key qualities include intelligence, initiative, innovation, self-confidence, communication skills, and the ability to coach employees. Profit is essential for a business to survive and grow by rewarding risk, enabling reinvestment, and allowing businesses to fulfill social obligations. Entrepreneurs should regularly self-assess their management style, organization structure, communication, production, marketing, personnel policies, finances, and relationships with external stakeholders to strengthen their business and overcome weaknesses. There are many sectors where entrepreneurs can start businesses, such as pharmaceuticals, insurance, tourism, banking, transportation, communication, education, food, garments, agriculture, and brokerage.
