Once you decide to start your own venture you know you need to prepare yourself by learning everything you can about the field you’re entering. But don’t forget that you also need the essential know-how about actually running a business. You don’t have to put things on hold while you further your education along those lines because you can apply for an MBA before graduation. You’ll broaden the general scope of your knowledge and gain new tools for effective communication, analytical thinking, and creative problem-solving that will be invaluable as you grow your business.

Beyond the research and book learning, though, to be a successful entrepreneur takes self-confidence, ambition, a solid work ethic, and the motivation to keep driving toward your goal even when obstacles get in the way. You’ve got to have the determination to get up every morning and go at it because, even on the days when you’d like nothing better than to pull the covers back over your head, no one is going to do the job for you if you don’t do it yourself.

Fortunately, a lot of others have gone before you to create their own successful (and mega-successful) businesses. When you need a boost, let their words support and motivate you:

“Whether you think you can, or think you can’t – you’re right.” -Henry Ford, Founder of Ford Motor Company

“The critical thing is getting off your butt and doing something. It’s as simple as that. A lot of people have ideas, but there are few who decide to do something about them now. Not tomorrow.

On What It Takes to Be Successful

On Other People

“Don’t let the noise of other people’s opinions drown out your own inner voice. Have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.” -Steve Jobs
