Most people, upon hearing this, feel the weight of nihilism. If nothing changes, if everything is just a looping cassette tape, then what’s the point? Why strive? Why love?

You don't have to believe in cosmic physics or infinite time loops to use this idea today. Use it as a secular filter.

Imagine, for a moment, that you are living your life not for the first time, but for the infinite time. Imagine that every breath you have taken, every word you have spoken, every secret guilt you have harbored, and every joy you have felt has happened exactly as it is happening now, an infinite number of times in the past, and will happen exactly the same way an infinite number of times in the future.
