Episode: 3439: The Golden Rule of Personal Finance
Featured Blogger: Jesse Cramer of Best Interest Blog
Date: January 29, 2026

This episode centers on the single most fundamental principle in personal finance: Spend less than you earn. Through vivid examples, relatable anecdotes, and behavioral insights, Jesse Cramer explores why this "golden rule" is both universally understood and widely unpracticed. Diania Merriam adds her own perspective, reinforcing that financial health doesn't come from income alone but from consistently applying this timeless principle, while also stressing the importance of investing the surplus.

Key Discussion Points & Insights

1. The Leaning Tower of Pisa Analogy:

[01:03]

• Jesse opens with a metaphor: the Leaning Tower of Pisa suffers because its massive structure rests on a shallow foundation.
• Insight: Just as buildings require a solid base, so do our finances. Without a strong foundation, instability is inevitable, regardless of scale.

“Every building needs a strong foundation. It applies to all buildings of all sizes in all locations. This brings us to the golden rule of personal finance, one that applies to all people at all levels of income: Spend less than you earn.”
— Jesse Cramer [01:23]

2. The Golden Rule and its Misapplication

[01:30]

• Cramer notes that everyone thinks they know this rule, but most have not internalized it.
• He cites examples of high-income earners (athletes, celebrities) who go bankrupt from overspending.

“How is that possible? They spent more than they earned. But surely someone with 100 million should be able to not spend all their money…overspending behavior is the classic slippery slope.”
— Jesse Cramer [02:11]

3. Personal Anecdote: Scarcity Mindset

[02:27]

• Jesse shares a story from a friend who, despite making millions in the NFL, still spends everything due to a childhood marked by scarcity—a “perfect storm” leading to a distrust of saving.

“Whenever I got money as a kid, it was like, spend it now or you might not get another chance to spend it…So now I just want to spend everything, save nothing. I don’t trust saving because I’ve never actually seen it work.”
— Jesse Cramer quoting friend [02:35]

4. Behavioral Economics and Lifestyle Inflation

[03:30]

• Jesse discusses how our minds justify personal overspending while criticizing others.
• Many believe an increase in income will prompt saving, but often, increased earnings simply lead to "lifestyle inflation."

“If I earned another 20%, then I’d start saving…but when the 20% comes, we buy clothes that are 20% softer, houses that are 20% bigger, or meals that are 20% more organic. The slope remains slippery all the way down.”
— Jesse Cramer [03:40]

5. Relativity of Spending & Judgment

[04:10]

• Jesse gives the example of spending $125 on a dinner: some view it as extravagant, others as quaint.
• Insight: Overspending and comparison operate at every income level—everyone both spends and judges spending in relative terms.

“We all look at people richer than us and think, if I were them, I’d be all set, because I’d never spend money like they do on that thing.”
— Jesse Cramer [04:49]

6. Building a Financial Foundation: Budgeting and Awareness

[05:20]

• Jesse reiterates that the key is not what you spend on, but that you spend less than you earn (preferably much less).
• He tracks his own budget and net worth, acknowledging it's easy to "pay lip service" to the golden rule but much harder to live by it.

7. Behavioral Hacking and Advertising

[05:45]

• He explains that advertising “brain hacks” us to think spending brings happiness when psychological research shows it does not.
• Maintaining discipline requires fighting the urge to spend, much like the effort to dig a deep foundation.

“Remind yourself that you’ve probably been brain hacked by advertising…out of spite towards advertisers, I actively fight my impulse to spend. It’s a struggle. I have to dig deep. Just like digging a foundation.”
— Jesse Cramer [06:20]

8. Host Reflection: Completing the Rule with Investing

[07:39]

• Diania Merriam concurs with Jesse’s golden rule but adds that one must invest the gap between income and expenses.

“Spend less than you earn and invest the difference. Our wealth is built in the gap between our income and our expenses. But we have to put that gap to work…our money can work way harder than we can.”
— Diania Merriam [07:41]

9. Financial Literacy Regardless of Income

[08:00]

• Diania emphasizes that income alone doesn't improve financial literacy. Managing small amounts is essential practice for managing large ones.

“If you can’t manage $1,000, then you definitely can’t manage a million dollars. And this golden rule of spending less than you earn applies, no matter how much money you do or don’t have.”
— Diania Merriam [08:06]

Notable Quotes & Memorable Moments

• “Spend less than you earn. I know you think you know what I’m talking about, but…most people think they know this idea, but they’ve not truly internalized it.”
  — Jesse Cramer [01:30]
• “Our brains work against us. This is a foundational lesson from behavioral economics. We criticize others for overspending, but find ways to justify our own similar behavior.”
  — Jesse Cramer [03:25]
• “Advertisers convince you that buying stuff will make you happy. Actual psychological research provides no such evidence. It might in fact make you unhappy.”
  — Jesse Cramer [05:50]
• “It’s important to remember that having more money doesn’t magically increase your level of financial literacy.”
  — Diania Merriam [08:00]

Summary

This episode distills personal finance to its essence: The only way to lasting wealth—across all income levels—is to spend less than you earn and, as Diania adds, invest the difference.

Diania’s closing reflection urges listeners that wealth is determined not by what you make, but by your actions and habits with money, reinforcing that everyone—regardless of income—must build their financial house on a solid foundation.

Your optimal life awaits—one solid step at a time.
