Everything depends on human effort, and words fail to win. The feeling comes from "doing everything wrong". Things succeed because they keep secrets. If you accidentally spill the beans and reveal the secrets, it will lead to failure.

The sentiment comes from the article "Everything is wrong, Wuli". The general idea is: the world is different, things have changed, and the ways and means of doing things have also changed.
