What she saw for herself was her own efforts. She thought that without her own efforts, the heavy objects would not rise by themselves. After all, leverage is a decoration, "the capital beyond the ability is zero."
In the eyes of others, her long pole is too conspicuous, and her words feel like a joke. Her so-called personal efforts/applications are insignificant, and the position is important. Ordinary people can take her place, "I can do it for me." Of course, it is impossible to prove whether the person who said this is really capable, because Sister Kobayashi and people in her same position can't exchange this experiment with others.
Others may think that it is a comprehensive result. They believe that this result has her own efforts, but it also has leverage. These people may have different views on leverage and her efforts.
I think most of the cognitive differences on this issue are still the disputes between these three viewpoints. Which viewpoint is correct may not have a standard answer.
In fact, it doesn't seem so important which viewpoint is correct, because no matter which viewpoint, it can't change the fact. Sister Xiaolin is like a fairy in the sky. She can completely ignore the saliva of ordinary people on the ground, and no amount of discussion may really shake her. And the person who said her, even if she thought "I can do it for me", no one really changed "I" to that high platform to verify it. After being impassioned, they still work honestly and can't change the reality. After all, we are just spectators on the Internet, and the ownership of leverage is fixed and cannot be changed.
