Your subjective sense that a year 'flew by' has nothing to do with clock time and everything to do with how many distinct memories you laid down. The mind has three selves: the anticipating self, the fleeting experiencing self, and the near-infinite remembering self. Repetition — the same commute, the same gym drive — gets compressed into one memory block, so long stretches feel like nothing. To expand felt time you deliberately manufacture novelty and intensity, because those are what the brain encodes as separate memories. The catch is that the present self is a saboteur: it takes the easy path and fixates on trivial discomfort, cheating the remembering and anticipating selves. So you treat experiences as investments — choosing the vivid option now because your future self will replay and be enriched by it, while trading a little efficiency for that variety.
Origin
Chris Williamson credits Laura Vanderkam's work on time perception as his biggest frame shift of 2019, layering in the future/experiencing/remembering-self model and Gretchen Rubin's suggestion to vary your route to work.
Core principles
- 01Everyone experiences the passage of time at the same speed; only memory differs
- 02Wishing for more time is really wishing for more memories
- 03The brain encodes novelty and intensity, and condenses repetition into a single block
- 04The present self is lazy and fixates on discomfort, sabotaging the remembering self
- 05Experiences are an investment in your future remembering self
How to run it
- 1
Audit your repetition
Notice which large chunks of your life have collapsed into single memories, like commutes or gym drives.
Pro tip If you cannot recall it, it did not add to your felt lifespan.
- 2
Inject novelty
Vary routines deliberately — a different route, a new setting — so the brain encodes distinct memories.
Pro tip Gretchen Rubin suggests occasionally walking or driving a different way to work.
Watch out Do not chase novelty so hard that daily life stops functioning.
- 3
Add intensity and emotional investment
Let yourself be fully absorbed and emotionally present in significant moments rather than half-there.
Pro tip Novelty or intensity — either one strengthens encoding.
Watch out The present self will resist the effortful, adventurous option.
- 4
Override the present self
Choose the vivid experience even when you are tired and the comfortable default beckons.
Pro tip Frame it as an investment: your remembering self will thank you.
Watch out The present self fixates on minor discomfort like sand between your toes; ignore it.
- 5
Remember on purpose
After an experience, deliberately reflect on and replay it so it is banked as a lasting memory.
Pro tip Reflection is what converts a lived moment into felt, expanded time.
In the wild
Chris cannot recall almost any of his commutes or gym drives from the year, yet vividly remembers the name of a man who put them on a boat in Africa 18 months earlier, the book he was reading, and the shoes he wore — because that moment carried both novelty and intensity.
→ A single novel, intense experience out-remembered hundreds of repeated hours.
Watching a sunset on Gili T with irritating sand between his toes, Chris notes the present self is annoyed, but the remembering self later recalls only the beauty, not the sand — proof that pushing through minor discomfort pays off in memory.
→ The discomfort vanishes from memory; the beauty is what endures.
Common mistakes
Letting the present self decide
Defaulting to the warm bed and easy option starves the remembering self of the experiences that make time feel full.
Chasing novelty without limit
Taking variety to an extreme sacrifices all efficiency; the method requires a deliberate trade-off, not total randomness.
Is it for you?
Best for
Anyone who feels time accelerating and wants their life to feel longer and richer in hindsight.
Not ideal for
Situations demanding pure efficiency, or people who would chase novelty to a reckless extreme.
From the transcript
“when people say I wish I had more time, what they mean is I wish I had more memories”
“your brain works well with novelty or intensity, those are two of the things that you can do to ensure that your memories are increased”
“you need to kind of almost use your experiences as an investment for yourself in the future”
