EVERYBODY WANTS easy answers. But often, things aren’t so simple, especially when it comes to financial conundrums. Consider the four common money questions below—and the rules of thumb that folks frequently rely on.
1. How much do I need saved for retirement? Type this question into Google and most of the answers will recommend that you save some multiple of your income. Some suggest eight-to-10 times income, while others recommend as much as 25 times.

HUMBLEDOLLAR ISN’T the financial website for everybody. Instead, it’s the place that folks end up after they have made their fair share of youthful financial mistakes—and they’re ready to settle down and get serious about money. I even briefly toyed with adding a tagline to the site: “Where Money Grows Up.”
What does grown-up money look like? It’s less about the size of your nest egg—and more about attitude. Here are 21 signs you’re a HumbleDollar reader:

When your neighbors show off their remodeled kitchen,

AS A LIFELONG perfectionist, it’s always painful to admit mistakes. When it comes to my finances, I’ve made plenty of good decisions. But I’m willing to confess to at least a handful of errors:
1. Not saving more when I was younger. When I got my first fulltime job, I was thrilled with the salary. I was making $16,000 a year—roughly twice what I’d been living on as a fulltime student.

I CAN ALREADY HEAR the groans. “Oh brother, here we go again with another of those religious wackos. I’m glad I don’t have to worry about all of that faith-based nonsense. My finances have nothing to do with faith.”
Really?
How about the guy spending his last dollar on a lottery ticket at the corner market? Or the victims of Bernie Madoff? Or the 65-year-old Enron employee fully invested in company stock in summer 2001?

ARE YOU GETTING RICH off your neighbors—or are they mooching off you? You might imagine your financial success, or lack thereof, rests squarely on your own shoulders. But much also hinges on the behavior of your fellow citizens.
In numerous financial situations, one group in society effectively subsidizes another. Much of the time, you want to be the recipient of the subsidy—but not always. Consider seven examples:

Spenders subsidize those who save prodigious amounts.

AT SEVEN O’CLOCK THIS morning, as my wife and I tried in vain to wake our children for school, we heard a similar response as we went from room to room: “My head hurts.” Nobody wanted to get up.
I have to say, I don’t blame them. It’s the middle of winter here in Boston. The sky is gray and the thermometer seems stuck below zero. It can be hard for anyone to feel motivated,

AS I WAS PREPARING for HumbleDollar’s January 2017 launch, my web developer suggested I add a mission statement to the top of the homepage. That mission statement morphed into a daily insight, which then became a daily Tweet that also found its way onto my Facebook page. Like the family that moves from a three-bedroom house to a one-bedroom apartment, I embraced the challenge of shoehorning financial ideas into 140 characters or less.

I AM AMAZED OUR schools don’t require kids to learn three important life skills: the basics of nutrition, a thing or two about parenting, and how to handle money. I’m no expert on nutrition and my parenting is a work in progress. But I do have a background in personal finance: When folks ask me what to read to deepen their financial knowledge, I have a ready list of titles.
Recently, however, someone asked me for a more advanced list—a “201”

I RECENTLY LEARNED a new expression, TL;DR, which stands for “too long; didn’t read.” Twitter users and bloggers use it when they want to summarize an idea for readers who are short on time. It’s the modern equivalent of saying, “Here’s the executive summary.”
Coincidentally, this week, two people separately asked me what I see as the most important principles in personal finance. In other words, they wanted the TL;DR version, without too much commentary.

WE MAKE ALL KINDS of financial mistakes: spend too much, borrow too much, buy expensive investment products, try to beat the market. To be sure, there are some folks who simply don’t know better. But others give the issue serious thought—and still act foolishly, justifying their behavior with cockamamie arguments. Here are five such justifications that I’ve heard in recent months:
 1. “It’s okay to spend money if it cheers me up.” This is the crack cocaine school of budgeting.

IF WE HAVE DINNER with half-a-dozen others, we might all share the same meal and yet each of us will have a different experience—sometimes radically different. Even as we talk politics, crack jokes and swap gossip, we’ll each have our own thoughts whirling in the background: errands we can’t forget, work issues we need to resolve, incidents from the day we keep replaying, worries we can’t put behind us.
For me, those whirling background thoughts often concern financial notions I want to write about.

WANT TO MAKE SURE your family is adequately protected against financial disaster? Try grappling with these 10 questions:

What’s the minimum dollar amount you need each month to keep your household running? That’s a useful number to know if you’re forced to slash living costs because, say, you lost your job or you need to cover a large, unexpected medical bill.
How would you cope financially if you were out of work for six months?

“STOP PULLING MY leg, Grandpa. You’re kidding, right? Is it really true that people:

used to believe they could beat the market?
paid 2% of assets and 20% of profits to hedge fund managers?
got their stock picks from a guy screaming on the television?
thought cash-value life insurance was a good investment?
believed that brokers would act in their best interest?
studied stock price charts to figure out what would happen next?
bought and sold exchange-traded index funds like crazy?

WANT TO EARN THE derision of the so-called smart money? Here are 12 ways to get yourself labeled a financial rube:

Express optimism about the stock market.
Stick with capitalization-weighted total market index funds.
Pay off your mortgage early.
 “Arnott vs. Asness? Missed that one. Was it on pay per view?”
Shun alternative investments.
Buy and hold.
Have no opinion on the economy and market valuations.
Dollar-cost average.
Own a target-date retirement fund.
Never cite Ben Graham,

OTHERS ARE LUCKY. But we deserve every penny we have, right? The distinction between “just deserts” and “just plain lucky” strikes me as far messier than we might initially assume. Consider just seven of the ways that we can be financially lucky or unlucky:
1. Birthplace. If we were born in the U.S. or another part of the developed world, we’re pretty much starting the 100-meter sprint within a few strides of the finish line,
