Here is a "Worry Table" I have been saving for a long time. I thought you might like it too.
Things We Worry About
Things that never happen.... 40%
Things that can't be changed by
all the worry in the world... 35%
Things that turn out better than expected... 15%
Petty, useless worries... 8%
Legitimate worries... 2%
Upshot: It's 50 to 1 against the worry being a real cause for concern.
Does that make you feel better? Now if only I can remember this the next time I worry!
