What are you sure of? What is it that you know that you know that you know?  

There is a saying that the only sure things are death and taxes. In fact, taxes are even surer than death as someone will have to file your last income tax statement for you even after you die. Life raises the stakes on each of us from time to time taking away our certainties.

• You are certain that you have the whole job thing under control until coworkers start whispering news that the company might not make it through the year.
• You are certain you've raised your kids well until the phone rings and it's the police.
• You are certain that your husband still has eyes only for you until he starts coming home later and seems distant in a way you can't quite put your finger on.
• You are certain that life is under control until a routine examination finds a lump and your doctor schedules a biopsy.  

Uncertainty has a way of creeping in on each one of us. Just when everything seems to be under control and life is working out right, something can come along and wreck it all, leaving you to wonder where you went wrong. What happened to that sense of control? What happened to that feeling that something was certain?
