Entreprenuership comes from observing real life buying/selling. U go to any market and observe who is making money, what customer's need. And learn more than u can in degree school. Also you need to buy some simple books on leadership, self development, 10 days MBA. And keep reading them again & again like bible. they prepare u more. If u can do short course on business even better. But basically to be successful business person u have to observe how things work, use common sense, serve your customers with innovative ideas with best product/services at least price and u r success. Business world is simple common sense not a dam rocket scince.
