The premise of "dedication and happiness" is "employment". Firstly, the author quotes Confucius' words and the story of Zen master Baizhang, and draws the conclusion that "all trades come first, and all evils and laziness come first", emphasizing that "having a job" is the foundation of being a man. When demonstrating the issue of "dedication", we first use Zhu's "respect is right" to explain that "dedication" means concentration and no distractions. Then, ask the question "Why should I respect you". . Starting from the need of human existence (working for life) and the meaning of individual life (living for labor), the author demonstrates the truth that "all professions are sacred and all professions are respectable". In the author's opinion, there is no difference between being a big president and pulling rickshaws in the sacredness of their profession. Therefore, "we have no choice about various occupations". As for what kind of work to do, it all depends on "how talented and how the situation is." As long as "a job is done completely, it is the first person between heaven and earth." Then, he asked: "How can I finish a work?" Again, "the only secret is loyalty" and "respect". The famous sayings of Zhuangzi, Confucius and Zeng, the comparison between carpenters and politicians, and the comparison between scavengers and soldiers all emphasize a truth: "Dedication is the most necessary and beneficial thing in life."

It is not enough to be "dedicated", but "happy and forget your worries" is the higher realm and value of life. When discussing the importance of "happiness", Liang Qichao first talked about the common sigh of "how hard it is", pointing out that life is alive and doing anything is laborious; For unavoidable things, it is better to have fun than to "do it with a sad face". "Any career is interesting, ... why?" Under this question, four reasons are listed. These four reasons are permeated with profound life experience and philosophy, and I believe that anyone who devotes himself to a certain job or affairs will feel the same way.
