"I walk on the ground, not dancing in the clouds" is a famous saying of Wittgenstein, which shows that he agrees with the steady and pragmatic pursuit of life and despises impetuous and rash life choices.

"I stick to the ground" can be understood as being calm and pragmatic about my career and life, step by step. "Dancing in the clouds" can be understood as impetuous, ethereal, and not supporting career and life. This sentence contains three philosophical angles: a calm and pragmatic life is the most beautiful; The illusory "dance" is the most terrible; Business is "empty" and life is doomed to be empty.

Wittgenstein's famous saying-you must keep silent about what you can't say.

Wittgenstein believes that when the object is unspeakable, it should remain silent. For example, a short philosophical theory, although only a few words, is difficult to explain thoroughly and clearly even if there are thousands of words, because at this time, people often have an understanding of it in their hearts, but they can't find the right words to explain the theory to their own extent, resulting in no way to explain the theory clearly.
