The seventh paragraph discusses how to be "dedicated". First quote the sentence in Zhuangzi and explain it. Then, give two examples: the carpenter makes the table, the politician builds the country, the dung collector cleans the toilet, and the soldier hits an enemy, which shows that no matter what he does, he must never be distracted (that is, "concentrate"). Then it discusses the harm of "disrespect" from the opposite side, points out that "dedication is the most needed and beneficial thing in life", and quotes the famous sayings of Zhuangzi and Confucius to further emphasize the importance of dedication. The natural combination of examples and quotations makes the reasoning of the article invincible.
