First of all, as a college student, thrift should be our spirit. In normal school life and study, hard work should be reflected in our study. We should do our job well, strive to improve our grades, learn professional knowledge and learn as many new skills as possible. This is a sign of hard work. Secondly, as adults, we are responsible for ourselves and our families. Therefore, it is time for us to consider solving some of our own economic problems through our own efforts and making use of our spare time. Reduce food waste and eat as much as you want. This is also a sign of thrift.
