How to See It

Negotiation & Deals

You're seeing Three Universal Currencies when a deal is framed not just in price but in "how much of your time" or "how much attention from your team." The other party may prefer to pay in time (e.g. co-development) rather than cash, or vice versa.

Product & UX

You're seeing Three Universal Currencies when product design explicitly reduces time or attention cost (one-click, defaults, fewer steps) and that is marketed as value — "save 5 hours a week" or "no more context-switching."

Strategy

You're seeing Three Universal Currencies when resource allocation is discussed in all three: budget (money), roadmap and hiring (time), and focus/priorities (attention). Misalignment often comes from optimising one currency while burning another.

Section 3

How to Use It

In any material decision, name what you're spending and gaining in money, time, and attention. Don't assume the other side values them the same way you do; offer and ask in the currency that matters to them. In product and ops, reduce time and attention cost where they're the real bottleneck — often that's worth more than a lower price.

Decision filter

"What are we spending or gaining in money, time, and attention? If we're saving money but burning time or attention, is that a good trade? And are we asking the other party to pay in the currency they have least of?"

As a founder

Frame asks and offers in all three currencies. Investors and partners may have more time or attention than cash — or the reverse. For customers, often the biggest cost is time or attention; if your product saves those, say so and price accordingly. In internal planning, budget attention and time explicitly, not just dollars.

Founders & Leaders

Charlie MungerVice Chairman, Berkshire Hathaway

Munger has long emphasised opportunity cost and the cost of time — "the best thing a human can do is help another human know more" — and has treated attention and focus as scarce capital. His lens is multi-currency: not just what something costs in dollars but what it costs in time and mental bandwidth. Founders can apply this by making money, time, and attention explicit in every major trade-off and by offering value in the currency the counterparty values most.

Opportunity Cost

Opportunity cost is what you give up when you choose one option. The three currencies make it explicit: every choice costs money, time, or attention (or all three). Frame opportunity cost in all three.

Reinforces

Attention

Attention is one of the three universal currencies — the gate for focus and decisions. Products and messages compete for it; strategy should account for how much attention you have and where it goes.

Tension

Trade-offs

Trade-offs are the reality of limited resources. The three currencies give a clear set of dimensions for trade-offs: you can often trade one for another (e.g. pay more to save time) if you name them.

Section 11

Summary & Further Reading

Money, time, and attention are three universal currencies. Frame exchanges and strategy in all three; offer and ask in the currency the other side values. Reduce time and attention cost where they're the real constraint.
