In Inc.'s September issue, columnist Norm Brodsky discusses his "Magic Number" (in other words, the key number he looks at to take the pulse of his business and make decisions for the future). Every business owner has at least one number that he or she looks every month, week, day or sometimes in real time.

Have you ever changed the number you were focusing on (for instance, from looking at "tons of widgets per day" to "boxes of widgets per day" or from "new customer rate" to "returning customer rate")? If so, I'd like to talk with you about it for a possible story.

Please email me if you are interested.
