Well, I've never put more than 40 hours per week into studying, often less. So a little job of 4 / 8 hours (two evenings or half a Saturday) mostly cuts in on social time. In return, you can afford to do more social things like go to a concert or a movie whenever you want. So I doubt it's detrimental. I really love tutoring. I'd rather work by thinking than by doing, and when I work I get to help people. I'm not in front of a class though, and the kids aren't in detention. That must be incredibly hard. The downside to my tutoring is that there's no work in the summer, when I (and the kids I tutor) have summer holiday. So I'm gonna have to find some work to do then.I would like my kids to appreciate hard work but I also would like them to recognize that studying is also hard work. I appreciate manual labor, I did a ton of it growing up. I would like my kids to know what it's like to put your back in to your living, but not at the expense of other pursuits.
