The Underrated Value of Doing Nothing

Intentionally doing nothing—no phone, no thoughts, no stimulation—can be deeply restorative. This practice, akin to mindfulness, helps reset mental clarity and appreciation for the present moment.

  • Doing nothing is a deliberate act, not laziness.
  • It allows mental recovery and presence.
  • Even brief periods of stillness improve well-being.

I sometimes literally do nothing and I think it's very valuable.

Time as a Scarce Economic Resource

Time, like money, is a finite and non-renewable resource. Every minute spent on one activity is a minute lost for another. This scarcity forces individuals to make deliberate choices about how to allocate their time, similar to financial budgeting.

  • Everyone has exactly 24 hours per day—time cannot be stored or earned back.
  • Spending time on one task means forgoing other opportunities.
  • Unlike money, time cannot be saved or reallocated once used.

We can only spend a minute or an hour or a second once and we if we spend it on one thing we can't spend…

Understanding Opportunity Cost of Time

Opportunity cost refers to what you give up when choosing one action over another. For time, this means every moment spent on one activity is a moment not spent on something else. This concept helps clarify why we should be more deliberate in how we use our time.

  • Opportunity cost is what you cannot do when you choose to do something else.
  • Time has no second life—once spent, it’s gone forever.
  • People often fail to account for the true cost of time, especially in meetings or commutes.

The opportunity cost is what you do not do when you do something else.

Mental Accounting Applied to Time

Just as people use mental accounting to manage money—dividing it into virtual budgets—we can apply the same principle to time. By assigning time blocks to specific tasks, we become more intentional and avoid wasting it on low-value activities.

  • Mental accounting involves creating virtual 'pots' for different uses of time.
  • Dedicating time to a task prevents overuse and improves focus.
  • This method helps avoid 'throwing good time after bad' on unproductive efforts.

We can dedicate time to a certain activity and not use it for something else.

Estonian Police's Time-Based Speeding Fines

In a behavioral experiment, Estonian police offered speeding drivers a choice: pay a modest fine or wait by the roadside for one hour. About half chose to wait, revealing how people implicitly value their time. This real-world test highlights the psychological cost of time versus money.

  • Drivers caught speeding could choose to pay a small fine or wait one hour by the road.
  • Roughly half of drivers opted to wait, indicating they valued their time less than the monetary fine.
  • The experiment reveals how people trade time and money in real-life decisions.

They gave him a choice between paying... or they could wait for an hour... and then they could be... they could go get didn't have…

Host · 00:00

About half of the people they stopped opted to wait... you can imagine from that how much these people value their time.

Why Donating Time Feels More Valuable Than Money

A study found that people view donated time as more praiseworthy than equivalent monetary donations, even when the money could achieve more impact. This reflects deeper social values around effort and visibility.

  • Donating time is seen as more valuable than donating money, even when monetarily equivalent.
  • Time donations are harder to make anonymously, increasing their social signaling value.
  • People find it easier to empathize with time sacrifices than financial ones.

In the eyes of others, the donation of time was seen as much more valuable.

Three Mental Models to Survive a Desert Island

When asked which three mental models he’d take to a desert island, the guest chose cost-benefit analysis for decision-making, optimism bias for morale, and mindfulness for presence and resilience.

  • Cost-benefit analysis helps make rational choices with limited resources.
  • Optimism bias maintains hope and motivation in isolation.
  • Mindfulness enhances sensory experience and emotional regulation.

I would take cost-benefit analysis... optimism bias... and mindfulness.

The Importance of Awareness in Time Management

Being aware of how we spend time allows us to make better decisions. Without awareness, we fall into autopilot mode, wasting time on low-value activities. Deliberate planning and mindfulness help us use time more effectively.

  • People often waste time because they don’t consciously track it.
  • Awareness enables better trade-offs between competing demands.
  • Mindfulness and intentionality improve time use.

It's about being conscious of time, being conscious that it's valuable and that you need to use it well.

The Double-Edged Sword of Deadlines

While deadlines make time salient and help focus effort, being too rigid can lead to suboptimal decisions. It’s important to weigh the true cost of missing a deadline versus the benefit of extra time.

  • Deadlines force awareness of time constraints.
  • Self-imposed deadlines should allow flexibility for better outcomes.
  • Rushing to meet a deadline may sacrifice quality or safety.

We should be careful not to treat [deadlines] as something that then becomes the dictator.

Planning as a Tool for Time Control

Planning isn’t about rigid schedules but about deliberate control over time. Whether using digital calendars or mental tracking, the key is intentionality—knowing what you’re doing and why.

  • Planning increases awareness and deliberate use of time.
  • Tools like calendars help, but mindset matters more.
  • The goal is control, not perfection.

It's about being in control of what you do when.
