Stapleton reduces two decades of personal-finance writing to a formula: spend less than you make and invest the rest in things you understand, and if you understand nothing well enough to invest, invest in yourself. He reframes the goal metric as time, not money: wealth is how long you could survive before changing your lifestyle if all income stopped today. By that measure a person earning a million a year but spending 990,000 has almost no wealth. The protective mechanism is human capital, the store of knowledge and skill that makes others want you. He argues it isn't a union that protects a worker but ten other employers who want to hire them, so the mission is to make your skills unique, marketable, and in high demand. Finally he warns against 'eating your children', consuming earnings rather than putting them to work in a business or assets you control.
Origin
Extracted from Modern Wisdom episode 148; Stapleton distils lessons from a decade running a trading and coaching business and echoes Morgan Housel's framing of wealth as unspent optionality.

How to run it
- 1
Reframe wealth as time
Ask how long you could maintain your lifestyle if all income stopped today; that runway, not your salary, is your true wealth.
Pro tip A high earner who spends nearly everything has very little wealth by this measure.
- 2
Spend less than you make
Create a surplus every period by keeping spending below income; this is the precondition for everything else.
Watch out We tend to live at our means, which is why most people never accumulate wealth.
- 3
Invest only in what you understand
Deploy the surplus into businesses or assets whose mechanics you genuinely grasp and can control.
Pro tip Stapleton reinvests most earnings into his own business because that's the return he understands and controls.
Watch out Chasing get-rich-quick tips in things you don't understand is how people give it all back.
- 4
Invest in yourself when you understand nothing
If you can't yet invest wisely, build human capital, your store of knowledge and skill that gives you market value.
- 5
Make yourself indispensable
Sharpen unique, marketable skills so multiple employers or clients want you, which is what actually protects your income.
Pro tip Be the person the company can't let go: 'if Tom goes we might as well shutter the company.'
In the wild
Stapleton illustrates the time metric with a stark case: someone who makes a million dollars a year but spends 990,000 of it. On paper they look wealthy, but by his definition they have almost none, because if their situation changed they couldn't survive long at all. Contrast that with someone whose spending is well below income and who has assets they understand working for them; even on a smaller salary they hold months or years of runway. The lesson reframes financial security away from income and toward how much time your resources buy you.
→ Listeners recalibrate from chasing income to accumulating runway and human capital.
Common mistakes
Living at your means
Scaling spending to match rising income guarantees you build no runway and stay perpetually one shock from ruin.
Eating your children
Consuming earnings instead of putting them to work in a business or understood assets forfeits compounding and long-term security.
Is it for you?
Best for
Earners who want durable financial security in a fast-changing economy rather than status spending.
Not ideal for
People needing tactical portfolio allocation or advice on specific instruments.

“spend less than you make and invest the rest in things that you understand”
“wealth is measured in time not dollars so it's a question of if all of your income stopped today how long could you survive”
