There's a post about Li Yizhou that says his secret is very simple: copying.

Although Li Yizhou is disliked for selling courses and harvesting retail investors, his approach is worth reflecting on. This guy's net worth could be over 100 million now.

The story goes that he previously had entrepreneurial debts of tens of millions (possibly just persona building, may not be entirely true—people exaggerate millions into larger figures anyway), and then he got the idea to do short videos. He started by mass-copying content, high-fidelity copying.

And this guy really does have strong execution ability, which I don't have. I tend to procrastinate a lot.
