After turning 30, it feels like you’ve already lived through two-thirds of life, because day after day keeps repeating and your brain is too lazy to think anymore.

The brain encodes new information more densely, and it estimates how long time feels based on the amount of information stored in memory. During the fresh period, you record more details—so looking back makes it feel like, “This took forever.” Repetitive days leave almost no new memories, and they get compressed into a blur.
So I want to go out as much as possible, talk to more interesting people, and use fresh inputs to stretch those compressed days back out again.
