Wow preparing already? I'm sure you deserve a break!
Maybe just take time to relax these holidays and recharge for the next semester. You'll be fine!
While recharging is definitely important (and burnout is the worst), sometimes I find watching lectures over the holidays to get an edge on the new semester
is relaxing (and also super productive) because there are no deadlines, there's no pressure to learn things, you're just free to explore the subjects at your own pace. If the subject is something I'm deeply excited to learn about, I find this kind of zero-stress study waay better than the assignment grind of a semester, and it can even take some pressure off that. So what better way to recharge, right? (obviously not for everyone)
