The core idea of retirement is this: You frontload your attention spent on money to generate wealth. You then offload your wealth to spend your attention on leisure, purpose, or love.

Retirement is our clever way of extending the Nothingness of Money out while we are healthy enough to appreciate it. We work hard in our youth so that we don’t have to when we’re older. We no longer have to be on a deathbed to fade money out of our thoughts, as we can do that with decades left to spare.
