Are you an online seller? Congratulations: you’re also an entrepreneur! What is an entrepreneur? It’s someone who starts a business, regardless of how small or large. You are undertaking a business venture and you are looking to achieve success. Being an entrepreneur isn’t the easiest job in the world (although it’s one of the most rewarding). Starting a business requires a great deal of blood, sweat and tears: the payoff, however, can be earth shattering.
