The greatest piece of advice I've ever received was that behind every fear is a person you want to become. If you're afraid to start your own business it is because you want it so badly that you don't want to fail at your dream. Let me tell you that it is impossible for a person to fail at their dream. A job at another company will always be available but the chance to live out your dream fades every day you procrastinate it. Live YOUR dreams instead of someone else's.
