Urban's model treats subjective time — not clock time — as the thing you actually experience and therefore the thing worth maximizing. The mechanism is memory: the brain only forges a new 'memory unit' when it encounters novelty, so a routine weekend evaporates ('felt like a second') while a weekend of travel, new people, or adventure feels like an eternity in retrospect. Because the felt duration is longer, you have in a real sense lived more. Someone who continually seeks novelty can feel like they live three times the subjective time of someone locked in routine — 'tripling your lifespan.' Novelty pairs with intensity and often discomfort, which is why the effort-averse part of us resists it. The remedy is deliberate: inject small novel experiences constantly, and use the tomorrow test — will future-you be glad you went?
Origin
Extracted from The Modern Wisdom conversation, where Tim Urban frames novelty as a way to 'triple your lifespan' and Chris Williamson illustrates it with the memory density of a first trip to Africa.
Core principles
- 01Clock time is roughly fixed, but subjective time is elastic and is what you actually live.
- 02The brain forges memory units only for novel input; routine leaves no trace.
- 03Novelty and intensity slow the felt passage of time; routine speeds it up.
- 04A weekend of new experiences feels far longer than an identical weekend of routine.
- 05Novelty needn't be exotic — small deviations from routine count.
How to run it
- 1
Reframe time as subjective
Accept that your felt experience of time, not the clock, is your actual lived reality — so expanding subjective time means living more.
- 2
Understand the memory mechanism
Recognize that routine requires no new memory units, so it compresses; novelty forces the brain to record, so it expands felt time.
- 3
Inject deliberate novelty
Regularly try something new — a hobby from the hardware store, a new instrument, an unvisited museum, a 45-minute drive to a new restaurant.
Pro tip It doesn't have to be gorillas in Africa; small, accessible novelty works.

Lean into intensity and discomfort
Favor experiences with some emotional or physical intensity, since the most memory-dense moments are often the uncomfortable, out-of-comfort-zone ones.
Watch out The couch and the phone feel comfortable but leave no memories — comfort is not the same as enjoyment.
- 5
Apply the tomorrow test
When the effort-averse voice says 'stay in,' ask whether tomorrow-you will be glad you went, and let that decide.
Pro tip That resistant side makes short-term decisions that don't serve you; treat it as unwise, not authoritative.
In the wild
Williamson recalls arriving in Uganda after 24 hours of travel — a plane, a safari truck, a boat — and meeting a guide he calls Morris. Years later he remembers Morris's shoes, the ornithology book in his hand, the sound of his steps on the muddy track, gorillas in the jungle behind him. Yet he can't recall the 16-digit number of a credit card he's had for four years. Full novelty and intensity burned an endless litany of arbitrary details into memory.
→ Total sensory novelty maximized the felt duration and left vivid lasting memories.
Urban contrasts a weekend spent working and watching TV at home — Friday to Sunday night felt like a second — with a weekend spent traveling somewhere new or at a wedding, which by Sunday night feels like an eternity has passed since Friday. Same clock time, radically different lived time.
→ The novel weekend delivered more subjective life from the identical two days.
Common mistakes
Mistaking comfort for enjoyment
The couch and phone feel seductive but are comfortable, not enjoyable, and leave no memories — so they quietly speed up your life.
Waiting for exotic novelty
Believing novelty must mean a big trip means you rarely do it; small local deviations from routine deliver most of the effect.
Is it for you?
Best for
People whose weeks blur together and who want to feel like they're living more, not just longer.
Not ideal for
Someone who genuinely thrives on stability and finds forced novelty stressful rather than enriching.
From the transcript
“someone who lives full of Novel experiences... they actually live like three times the amount of subjective time that someone who kind of just sticks…”
“novelty and intensity seem to be the two things that kind of slow down our subjective experience of the time”
“we often mistake a comfortable activity for an enjoyable one”
