Why Worry?

Is concern over the past or the future a major source of stress in your life? Consider the conclusion reached by a woman who came to the sudden realization that fears were ruining her peace of mind. She took a pencil and made a tabulation of her worries, estimating as well as she could their nature and origin. These were her conclusions:
40% - will never happen; anxiety is the result of a tired mind.
30% - about old decisions that I cannot alter.
12% - others’ criticism of me, most of it untrue.
10% - about my health, which gets worse as I worry.
8% - ‘legitimate’ since life has some real problems to meet.
Adding it up, 92% of that woman’s worries were unproductive. What would your worry balance sheet look like?
