In many areas of our lives uncertainty is inevitable. You will cause yourself much needless pain if you unrealistically demand certainty. Even in extremely important areas of our lives we are likely to be uncertain.

If you can let go of unrealistic demands for certainty, you will actually achieve more peace of mind than if you were certain!

What is the proper attitude? Try to be as certain as possible, and accept that any remaining uncertainty will not exacerbate your situation.
