How to live a longer life, subjectively rather than objectively.

Notable quotes:

But why does a week long foreign holiday, which is not routine, feel like it has flashed by? Surely a week like that should feel long, but it doesn’t? Well, let me backtrack and say it is not strictly “routine” that speeds up subjective time, rather it an absence of novelty. Novelty is what slows time down, and a routine is an engine for eliminating the unexpected, thereby eliminating novelty.
So the true antidote to subjective time speeding up is to inject new, different and surprising things into life.
