Entrepreneurship is a mindset. An entrepreneur is someone who embraces critical thinking, innovation, and change rather than waiting to adapt to changes as they occur. Entrepreneurs who operate within an organization are looking to add value; they are open to advice from mentors and managers and proactively seek innovative solutions. They take full control of their career paths. Strong business leaders understand that human capital is the most valuable asset they have, even though it often does not show on the balance sheet, and that the best employees are the ones who are proactive, not reactive. These are the people who make the clients and customers happy.
