The words passion and vision are used as maxims in business though their central role to success in the same is debatable. In case an entrepreneur did not have either, it is not possible to just suddenly build up the same. Business research conducted by professors at the MIT Sloan School of Management concluded that it is much more important to execute a vision rather than simply dreaming up. Before waiting for the right idea to come to mind, it is essential to simply let go and start something. A look at some of the great entrepreneurs over the years shows that none of them were crystal clear as to how things would shape up over the years. This includes giants such as Michael Dell, Mark Zuckerberg, Steve Jobs and Bill Gates. They all had the desire to succeed and eventually figured out the right path towards success, but never waited for that eureka moment.
