Do one thing and love another. In other words, we should take our work seriously, do our duty, love our jobs and be dedicated. First of all, morally speaking, "doing one thing and loving one thing" is the basic requirement of socialist professional ethics and the embodiment of selfless dedication. As college students in the new century, we need to put the interests of the motherland and the people first. No matter what work we are engaged in, we should actively participate in it, dedicate ourselves and realize our own value. Secondly, from a practical point of view, although China has developed rapidly with the efforts of many devotees who "do one thing and love one thing", the employment situation is not optimistic due to population pressure. In the increasingly fierce competition, it is even more difficult to find a job that satisfies you. Moreover, people's plasticity is very strong, and interest is also cultivated. If you do a job with your heart, you are sure to get pleasure from it. If you don't work hard, you won't fall in love with any job, and eventually you will accomplish nothing. Thirdly, from our own point of view, most students' majors are assigned, but with the deepening of study, many students have fallen in love with their majors. If we don't study it, how do we know that we won't fall in love with it? We didn't choose to give up studying to prove that we support the spirit of "doing a job and loving a job". Therefore. We should do what we do and love what we do.
