In recent years, new concepts have emerged endlessly, from blockchain to AI and short-form video commerce. Many people watch others' stories of sudden wealth, always fearing they'll miss the wind and be left behind by the times.

But flipping through thousands of years of human history, you'll discover that the fundamental logic of making money has never changed.

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

Another foolproof way is selling water and shovels. In gold rushes, the real fortunes weren't made by gold miners, but by those selling tools and supplies.

The more people chase wind, the more those providing them basic services and tools can avoid risks and profit steadily.

And all great wealth that transcends class involves leverage—earning money by purchasing others' time. Workshop masters hiring apprentices, tech leaders organizing programmers—all use capital to mobilize others' energy, breaking through individual time limits and achieving wealth-scale leaps.

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

Rather than anxiously chasing trends, why not settle down, find your own information gap, become the "shovel seller" in the wind, and gradually transform from a spectator into a player capturing profits.
