How focused are your marketing efforts? Do your customers know exactly what you stand for and why and when they should buy from you? If they do, there is a good chance you can charge a premium for it.
Do you have an idea for a business that only you could execute? Why then would you offer up the idea to someone else who would mutilate your vision. Instead, keep it and develop it yourself. Your future customers deserve you, not someone else.
Do you have policies that your employees and customer hate? WHY DO YOU HAVE THEM? By removing them you can increase customer satisfaction, empower employees and increase efficiencies.
