There is an old saying: "Worrying won't stop the bad stuff from happening; it just stops you from enjoying the good."

Such wisdom! It is advice I take to heart and try to remember when I am facing a situation like we are going through today with the coronavirus pandemic.

Worry is the most destructive habit. I am as bad about worrying as anyone. I always think about what can go wrong with any project. Over the years, I have learned that worrying does not give you anything but wrinkles; something else to worry about.

Worry does not do any good. I know; most of the things I worried about didn't happen.

Worry is wasting today's time to clutter up tomorrow's opportunities with yesterday's troubles.

Dr. Charles Mayo, one of the co-founders of the Mayo Clinic, said: "Worry affects circulation, the heart and the glands, the whole nervous system, and profoundly affects the heart. I have never known a man who died from overwork, but many who died from doubt."

In my most recent book, "You Haven't Hit Your Peak Yet!" I wrote a chapter on "The Second Ten Commandments." The first of these new commandments reads: "Thou shall not worry, for worry is the most unproductive of all human activities. You can't saw sawdust. A day of worry is more exhausting than a day of work. People get so busy worrying about yesterday or tomorrow, they forget about today. And today is what you have to work with."

Dale Carnegie's "How to Stop Worrying and Start Living" has been one of my favorite books for the last 50 years. It was first published in 1948, but the advice it contains is just as fresh and valuable as it was then and is right-on for these uncertain times.

Two sections that really knocked my socks off were about businesspeople trying to solve problems without the added burden of worrying. Carnegie credits Willis H. Carrier (whose name appears on many of our air conditioners) with these silver bullets:

1. Analyze the situation honestly and figure out what is the worst possible thing that could happen.

2. Prepare yourself mentally to accept the worst, if necessary.

3. Then calmly try to improve upon the worst, which you have already agreed mentally to accept.

Also from Carnegie's book, this particular list describes how to "Break the Worry Habit Before It Breaks You":

• Keep busy.

• Don't fuss about trifles.

• Cooperate with the inevitable.

• Decide just how much anxiety a thing may be worth and refuse to give it more.

• Don't worry about the past.

I love this story of a little clock that almost worried itself to death. It worked itself into a frazzle thinking about how often it would have to tick in the coming year.

"I will have to tick two times per second, which means 120 times a minute, 7,200 times every hour and 172,800 every day!" Then it went further — 1,209,600 every week, and a whopping 63 million times, give or take, over the next 12 months! The more it thought about that number, the more worried it became. Finally, anxiety overtook the little clock and it stopped ticking.

And it was miserable. So it consulted a psychiatrist. "I just don't have what it takes to tick that often," it complained.

The doctor asked, "How many ticks must you tick at one time?" The clock replied, "Just one." The doctor suggested, "How about using your energy to just tick one tick at a time, and I think you'll be just fine."

So the little clock wound itself up, decided to take one tick at a time and ticked happily ever after.
