I love weekends, and not because I take them "off". Teachers very rarely get their weekends free. I do refrain from email and spending lots of time on the web, because that's just too time-consuming.
For me, weekends are about regrouping, relaxing, rethinking, and revisioning. I know it sounds silly, but I've learned that taking time on the weekend and literally planning it into those 48 hours can make the rest of the week a more pleasant experience.
On regrouping: It's literally about mental, physical, and emotional health. Teaching well takes a lot of mental energy. Planning, teaching, grading, and making sure you make it clear for students can be a real challenge, especially when the content is second nature to you (and not your students). It's physically tiring because I move around a lot, have a lot of meetings, run between office and classroom, home and work. And teaching is emotionally tiring because I am still learning (after 14 years) how much of myself to give to my students. I never feel like I give enough. With almost 100 students this semester, there is less of me to go around to each student.
On relaxing: I have to do it. Sometimes it's gardening. Sometimes it involves movies, sometimes time with friends and family, a run with the dogs (planned for as soon as I finish this post), sleeping, music, reading... Relaxing is good for body and spirit.
On rethinking and revisioning: Ok, so this is actually more like work, but it's a different type of work. It is primarily intellectual. I think about what I taught, how it went, my writing... And sometimes, I even get some writing done, which is a good thing because it's expected.
As for getting a little help from your friends: today Marley decided I couldn't complete this post without his help. Therefore he is the co-author of this post. Of course it took me twice as long to get this done with his help, but it's all good.
Sigh. It's a good thing it's Friday.
