This is a good time of year to take an overview of your business. Not only what you are doing but what can be improved? look at your accounting system, the process you use to store your product. your presentation method. Are these areas in need of improvement? are you using a current method? Not that you have to have it, but what is the cutting edge methods being used out there by others? I highly recommed reading Business 2.0 and Fast Company both magazines cover up coming companies and some new methods that they are applying tosometimes, old markets. - a great resource to get your mind set ready.
A smart business person will look at the methods that they use and see if it can be improved. if it can, maybe somebody else is looking for a solution - like the one you have created. find a need and Fill it. it is not always wise to rely on one single product. dervisify your business - Can you sell a method that you created for your business that others may pay for?
