Change goes both ways -- good and bad. Life works that way, too. Keeping a can-do "millimeter" mindset even when the change is negative means understanding that if something goes south, small efforts to move it north work, too.When it comes to business, I have a quick tip on how to handle the difficult moments. Let's say you have clients or patients. A client suddenly decides to stop doing business. What is your attitude? Do you let it defeat you in a BIG way or do you have a "millimeter" attitude, which means one, small shift in your attitude to change your outlook. Do you want to hear a good one? It's small! It's simple! It's easy. One word: NEXT! Don't dwell. Move on. A client or customer quits, you just immediately focus on the one, simple next move. Don't get bogged down in disappointment or ask why? It would be good to ask the client why, listen to it, don't argue it, but realize that is their perspective. Take something you can use to improve, and then move on.
