How can you slow down life? (which is perceptually half over by 23)

From Sam Altman on Twitter https://x.com/sama/status/910895248724828160:

From a psychologist friend: “Adjusted for the subjective increase in how fast time passes, life is half over by 23 or 24. Don’t waste time.”

The perceived acceleration of time as we age is a major cognitive illusion. Childhood memories seem endless because they were filled with constant discovery and the impairment of registering regret or anxiety about the past and future. Adulthood doesn’t hold the same level of novelty.

Learning new things and taking on challenging cognitive tasks can potentially slow our internal sense of time.

Trying new fruits, exploring different sports, subscribing to new forms of thought and radically new lifestyles add layers of childlike richness.

In my lived experience, the times when I was learning new things and been outside my comfort zone definitely felt slower than when I was doing a routine that I was already great at.

Connecting this to another topic, this might be a way to detect if you’re not engaged in deliberate practice (the best way to learn): does the practice feel like it’s taking forever, or does it feel like time flies by?
