“Worrying doesn’t get you anywhere.” Or so they say, “they” being the anonymous group of trolls in my head that churns out stuff like that.
But worry does have a use. It urges me to take action. Because of worry, I do things today that I’d ordinarily put off to tomorrow.
I admit, worry makes today (and all preceding time before the event of which I am worried about) potentially nightmarish — the anxiety I feel in the grips of persistent worry isn’t particularly pleasant. But that might be a small price to pay in being as prepared as I can be in anticipation of that worrisome event.
The more I prepare, the less worried I get; till I know that I can prepare no more. That’s when worry ceases to be useful, and itself becomes a cause for concern.
