The most impressive entrepreneurs almost invariably achieve their high levels of success by starting small and building on their accomplishments. Through work and dedication, they develop their skills as they forge ahead with their ambitions. Having an MBA degree can certainly expand your chances of reaching financial success, but you need more than a degree to become a role model for other entrepreneurs. If you want to build your own business, you’ll need to acquire skills that you can learn only on the job.
