We are usually tired after we finish a long day’s classes, so I think we should have a good relaxation after classes. But our life will be a mess if we take part-time jobs besides studies. I notice that some students are late for class or look sleepy in the class, because they need to work in an uncertain time and it means they need to work at night sometimes. They earn money without caring for their health, so they easily feel tired or get sick after a stressful day.
