The only current era dividend is:

Keeping your body healthy.
Because what everyone is “competing” for now isn’t jobs, houses, or cars—it’s a good mindset and deep sleep duration.
When everyone else is thrashing around in the mire of information overload, anxiety, and insomnia, being able to eat well, sleep soundly, stay emotionally stable, and have abundant energy一—that alone is a form of dimensionality reduction.
Your body is the most hardcore production asset and safety asset you have in this era.
There’s another even more critical reason: the “longevity dividend” brought by an explosion of technology is only left for those who can live long enough—and who can catch it.
