I don't think a lot of people know how to have free time. I mean, look at the way people "vacation" or spend their weekends. It would take a while for them to adjust.
True. As a teacher, there are portions of my life (summer) where I have an unusually large portion of time off. Maybe it's because I'm used to it, but I don't have too much difficulty finding things I enjoy doing. Unfortunately, I also find a larger portion of my work becoming bullshit time spent. I now am expected to prove that my students have learned in ways beyond grading assignments and providing written feedback. I now must prove, with several Excel worksheets, that the kids are now able to do more than they could before I started teaching them as well as meet arbitrary goals that are set as "adequate learning targets". As if we actually can take a large group of individuals before instruction and reliably determine how much they will learn. Oh, also, there is no research available proving that collecting data in such a way improves student outcomes. More time spent on data collection and displays takes away from actual engagement with my students and/or planning creative learning experiences.
