6. Employee vs Business Owner

When you work for a company, you have a clear job description. You have a manager who oversees your work and corrects you when needed. In that situation, it's hard to stray because if you think or act outside the "box," there are corporate / bureaucratic mechanisms that will alert you.

But when you run your own business, the chances that you will make mistakes are much greater; this makes sense, since there is no boss to oversee your work. You are your own boss.

This is why it's so important to have a clear system, and to use that system to manage your company on a day-to-day basis.
