As an entrepreneur there are two routes you can take: either create a service-based business where you trade your skill or knowledge for money or create a product-based business where you sell products to people. If the successful business is offering a service, it typically takes less money to start and has a smaller upside in regards to scale unless you can duplicate the service offering on a repeatable basis. The successful startup business offering a product potentially takes a lot more money to start but has more upside with respect to scale and repeatability. You can design one product and sell it it thousands of times.
