Management is a large part of your job when you own your own business. If you feel that your management skills are lacking, then you should hire someone to help you out from the beginning. Bad management has caused many good businesses to fail.
Not everyone is cut out to be a good manager. You may be very good at real estate, but that does not mean you can manage people well. Consider hiring an office manager that handles the management tasks for you or outsourcing work so you do not have to worry about managing a staff.
You have to focus on what is best for your business. In order to do that, you have to think about management right from the start. Do not fail before you even get started because of bad management choices. Take an honest look at yourself and decide what the best route is for your business.
