The four most important characteristics of successful entrepreneurs are product/customer focus (this focuses on the two most important parts for any business, the product or service being sold and the customers who will buy it.) , passion for their business (their love for their business and industry combined with a strong belief that it has an important role int he world), a tenacity that is fierce even in the face of failure (it is difficult for entrepreneurs to begin a business and they will face many setbacks on the road to success, it is important they are able to remain focused on their goal and keep marching forwards no matter what ), and the intelligence to execute their plans (to execute a successful business they would have plans, goals, models, and much more like raising money to begin the business and establishing partnerships).
