Over the past two years, new concepts have emerged constantly—from blockchain to AI, short-form video commerce. Many people watch others' stories of sudden wealth and fear missing the next big wave or being left behind by the times.

But if you flip through thousands of years of human history, you'll discover: the underlying logic of making money has never really changed.

The oldest method is information arbitrage—moving cheap resources to scarce places and selling them at premium prices. Ancient salt merchants and tea traders made regional profits via the Silk Road. Today's cross-border e-commerce and knowledge monetization follow the same principle. Whoever grasps information others don't know gets to profit first.

There's another reliable way to make money: selling water and shovels. During gold rushes, the real fortunes weren't made by the prospectors, but by those selling tools and supplies.

The more people chase every trend, the more those providing basic services and tools to them can avoid risk and profit steadily.

And any substantial wealth that transcends class requires leverage.

Make money by purchasing others' time. Workshop owners hiring apprentices, bosses organizing programmers—they all use capital to mobilize others' energy, breaking through the ceiling of personal time and achieving a quantum leap in wealth.

There's nothing new under the sun. Human nature doesn't change, so the logic of making money won't either.

Rather than anxiety-chasing every trend, it's better to calm down, find your own information advantages, become a "shovel seller" in the craze, and gradually transform from a spectator into a player who gets a slice of the profits.
