ON APRIL 14, 1988, Captain Paul Rinn was the commanding officer of the USS Samuel B. Roberts when it struck a mine in the Persian Gulf. The resulting explosion tore a 21-foot hole in the side of the frigate. Almost immediately, the ship began taking on water and multiple fires broke out.
Naval protocol for this situation was clear: Put out the fires first, then worry about patching the hull. But after just a few minutes of firefighting,

ONE OF MY FATHER’S favorite sayings was, “This too shall pass.” Recent events have made me dwell on its meaning—and wonder where the phrase came from.
It seems to have originated as a Persian adage. It was employed in a speech by Abraham Lincoln before he became the 16th president: “It is said an Eastern monarch once charged his wise men to invent him a sentence, to be ever in view, and which should be true and appropriate in all times and situations.

THE CORONAVIRUS IS prompting people to behave irrationally. They’re hoarding food, toilet paper and other goods. They’re risking their health—and that of those they know—by failing to limit their physical contact with others.
This irrationality has spilled over into the stock market. More than 30% of the U.S. market’s total value has been wiped out. It’s hard to argue that this is justified. The businesses represented by these stocks may be hit with short-term disruptions and a temporary reduction in profits.

WHEN I WENT TO THE grocery store last week, it was packed with customers stocking up on essentials. Carts were filled with items that people couldn’t possibly consume in any reasonable period of time. It’s a scene that’s been repeated across the country.
A friend told me: “When people panic, they want things right away. When people see other people panic, they panic, too.” Like the coronavirus, fear is highly contagious.
I’m not panicking,

WHILE JIM AND I cooked dinner the other night, we talked about the old cars we drove when we were younger—and how they tended to pull to one side if we took our hands off the steering wheel. We humans have a similar tendency: We head in one direction unless we make a conscious effort to be more rational.
That brings me to the coronavirus and accompanying stock market plunge. We all have gut reactions to news like this.

HERE’S THE LEAST surprising thing you’ll read this week: You can’t control the financial markets. They’re driven by news—and we simply don’t know what news we’ll get in the weeks and months ahead, whether it’s about the spread of the coronavirus, its impact on the global economy or something else entirely.
But don’t despair: There’s also much that we can control, including how much we save and spend, the amount of investment risk we take,

I’M WRITING THIS just before 6 a.m., following a few days during which world stock markets caught their own version of the flu. Frankly, I can’t sleep thinking about what’s happened—and especially about the investors who panicked and locked in their losses, just like so many folks did in late 2008 and early 2009.
It took me a few minutes to muster the courage to look at my 401(k). When I did,

HOW OFTEN DO YOU think about money? Hey, you just did. Seriously, we think about money every day and sometimes every hour. Some studies say we ponder financial matters even more often than the old standby: sex.
We’ve been thinking about the stuff for a long time. Money goes back about 3,000 years. Paper currency can be traced to China in 700 BC. They didn’t fool around: Their currency stated that all counterfeiters would be decapitated.

ONE OF MY FAVORITE movies of recent years was Hidden Figures. There’s a pivotal scene where the hero, Katherine Johnson, realizes they need to use an ancient numerical technique known as Euler’s Method to solve the trajectory equations for John Glenn’s mission. This involves breaking a complex problem into very small pieces, solving each part, and then summing them to get the solution.
Over my engineering career, I used various numerical integration techniques to solve complicated problems.

FROM AN EARLY AGE, I was amazed at the power of mathematics to model our world and solve real world problems. In engineering school, we studied a host of mathematical techniques that did just that. But I wish we’d spent more time on probability and statistics.
In 1989, I read a book that gave me a broader view of how probabilistic our world is and, at the same time, made me aware of how ill-prepared the general population is to understand these concepts.

BEATING THE STOCK market over the long term is no mean feat. Only a tiny proportion of investors—professional or otherwise—manage to do it. So why do so many people think they can?
Meir Statman, a finance professor at Santa Clara University, cites eight key reasons. In a new monograph titled Behavioral Finance: The Second Generation, he slots these reasons into two broad categories—five cognitive and emotional errors, followed by three expressive and emotional benefits:
1.

I USED TO THINK anybody could be taught to manage money sensibly. I no longer believe that.
When I was in my 20s and scraping by on a junior reporter’s salary, I had some sense for the financial stress suffered by everyday Americans. But after a handful of years of diligently saving, I was able to escape those daily worries. Many Americans, alas, never do.
This was hammered home when I recently took the financial well-being questionnaire offered by the Consumer Financial Protection Bureau (CFPB).

WHY DON’T WE SPEND our time and energy on financial issues that have the greatest impact? We’ll drive to a more distant gas station to save 10 cents a gallon, but fail to do all the maintenance needed to extend the life of our car. What lies behind this sort of behavior? The savings from getting the best price per gallon is concrete and immediate, while maintaining our car is long term and abstract.

MONEY HAS ALWAYS caused me stress. As a child, I worried my parents didn’t have enough, even though I had no idea what sum would have been considered enough for our family of six. In college, I worried about accumulating debt. I ended up living so frugally that I managed to save nearly all of the Pell grant that the government awarded me. I not only graduated debt-free, but also had a sizable emergency fund in place as I moved into adulthood.

“RESOLUTE” IS THE wrong adjective to describe most of us at the start of a new year. We know what we should be doing for our future self. But within weeks, days and sometimes hours, we forget about the person we’ll become.
What can we do to improve our odds of success in 2020? As Stephen Covey taught us years ago in The Seven Habits of Highly Effective People,
