But ....what about college students???? People rarely talk about the fact that college students can be as stressful if not more stressful. In graduate school, students are expected to work/study almost all the time... Should we also have a reduce in our work/study load?
You could in principle do the same. I'm currently in a Masters program and have been doing what this link describes since I first started university: Four or five hours of very focused work each day, followed by real leisure time.
Granted, it might be different if I were doing a PhD, but at least up until where I am now this has worked perfectly. I get done just as much while being less stressed and feeling a lot better about life.
