Entrepreneurship involves starting and running a new business, which is often a small business initially. An entrepreneur takes on the risks of starting a new venture to potentially profit from their ideas. There are four main types of entrepreneurship: small business, scalable startups, large companies developing new products, and social entrepreneurship focused on social needs over profits. Successful entrepreneurs tend to be willing to take risks, innovative in creating new ideas and processes, and have a clear long-term vision for their business combined with strong leadership and flexibility.
