Resolve to focus on what is “wrong” in your business.  Each week, identify two or three small things that are “wrong” with your business (kind of like Jeff Bezos does), and fix them by week’s end.  If you want to think more positively, identify three things that are “right” and take the week to make them incrementally better.

Here is last year’s resolution (one of my favorites):

Prepare a list of client commitments and stick to them.  Include returning phone calls within a specified period of time.  Send the commitments to clients with every bill.  Offer discounts if you don't live up to any of your commitments.  Give clients a small discount if they send back a "Report Card" with their payment.  Make it look like the ones kids got in the fifties.  Follow up with them on any grade they give below an "A."
