How can you, as a small business owner, figure out what you are and, from there, begin to take action? Simple - you have to understand what part of the job you are doing and, if it isn't fulfilling the role of the entrepreneur in your business, you must make the decision to take on that role.
Look at what is average in your area, your industry, and your company and then be better. That could be as simple as reading another book each month or attending a seminar each year. On the other hand, it also means acknowledging what 'average' actually is and how you, as the owner, arrive at that figure.
