Nothing can happen without tenacity, fortitude, and courage. Be bold enough to make choices; don't just let things happen to you. Though you cannot have control over everything, you can focus on what you can handle and influence with your actions in a given situation. You have the power to make decisions that will move your business forward. You should not feel daunted by your lack of knowledge of business strategies either. You learn and grow while building your business.
What is stopping you from believing in the business of your dreams? Insecurity? Fear? Lack of confidence? All of the above? How can you overcome these obstructions? You need to work with conviction. Being a dreamer does not mean that you can't also be a doer. In fact, having a dream is the starting point for building your dream business.
